Even if telling a lie is in your best interest, it would bother you to be caught lying. It would reduce your credibility in the future, so you would avoid telling stupid and obvious lies that are bound to be exposed. [Emphasis added, ed.]It's true that spiritually normal people would be bothered to be caught lying, but that's not how SJWs are because SJWs are cowards at their core. Worse yet, this cowardice starts with the best of intentions, albeit childishly naive intentions.
SJWs are human beings, which means their motives are often quite human. In this particular instance, I'd imagine that the descent into SJWism tends to start with the typical human desire to be accepted as part of a group.
With a few notable exceptions, most human beings wish to belong to something. Belonging is the fundamental source of human contentment. Children wish to belong to their parents (especially fathers), which is why children from broken homes have so many issues. Women typically wish to belong to men, which is why single women seem more neurotic than married women, and why the typical woman seems to become less neurotic after marriage. Men also like to feel a sense of belonging, which is why they often join tribes or the modern equivalent: organizations. Belonging to someone or something and knowing one's place within it creates a sense of peace, and the absence of belonging--isolation--creates a sense of unease.*
It is within this framework of human motivation that the seeds of SJWism are planted, for the start of this problem is that of cowardice. Specifically, SJWs fear social ostracism, probably to an atypical degree. Thus, if one were to be asked by his peers for his opinion on a subject, he would likely toe the group line whether regardless of whether he believed what he actually said. He might even do this in spite of, say, having a track record of holding an opinion contrary to the group's generally held opinion on the matter. Thus, while he might be bothered to be caught lying, he would be even more bothered to directly disagree with the people whose approval he seeks.
Thus the game is started, and thus it progresses. One must subordinate to the group by affirming that one is just like everyone else in actions and beliefs whether one actually does and believes like everyone else. As this progresses, words are not used to convey information, but to placate people. The meaning of words doesn't depend on objective metrics, but on the effect they will have on the listener. Eventually, words exist to make friends feel good and enemies feel bad.**
Unfortunately, this quickly becomes a losing game in the long run because one destroys his credibility by constantly abusing language for social gain. One also becomes increasingly attached to the group whose approval he seeks because he has unwittingly isolated himself by his dishonesty, and so the only ones who will have anything to do with him are those for whose benefit he lies. I suspect that most SJWs come to realize this after a fairly short amount of time, which is why they often double down in their lies.
The reason they lie in the first place is to avoid social ostracism. Unfortunately, their lying precludes them from being part of any group but the SJW group. They have to double down because if they don't, they will be kicked out of the SJW group and then be completely alone. This is their greatest fear.
I also suspect that most SJWs know in their hearts that they are cowards, which is why they refer to themselves as Warriors, bravely fighting against injustice of all stripes. They fancy themselves to be knights of the modern age, upholding the chivalric code of a keyboard Camelot. SJWs, even in their descent into cowardice, still recognize the virtue of bravery and attempt to delude themselves into thinking that they are courageous. They are projecting a fantasy, but even in this fantasy they still recognize virtue even if they are lying to themselves about possessing it.
Unfortunately, their actions betray them. They destroy with words what has been built by hands. The fabled knight, on the other hand, would destroy with his hands what had been built by words.*** SJWs are lots of talk but almost no action. Yes, they write, tweet, post, blog, call, DDoS, etc. but this is merely words. Their conception of justice as put into action is to "raise awareness." Basically, they point and shriek.
At no point has any SJW done any work of substance to mitigate injustice. They don't build schools for minorities; they don't provide food, shelter or clothing for those cruelly laid off by evil capitalist overlords; they do nothing to help the oppressed build their own business and thus escape the evil clutches of the white cis male ruling class. Sometimes they have fund raiser drives, often quite snarkily, but it does not appear that they are ever the ones who actually do what needs to be done for those who are allegedly oppressed. In short, they are not brave enough to actually act. They try to hide this, though, behind a whirlwind of consciousness-raising activity.
While it is easy to have sympathy for SJWs because they just want to belong to something and are scared of rejection, it is foolish to tolerate their dishonesty and cowardice. Just as a caring mother doesn't let her child eat a steady diet of candy and cake, a caring society should not let its members be cowardly and dishonest.
For starters, cowardice can never lead to healthy relationships. Paradoxically, the fear of rejection guarantees rejection.^ One core insight of Game is that the man who is supplicating and works hard to not be rejected by a woman is almost sure to be rejected by her because he constantly demonstrates low value. This applies more broadly, though, in that "men are men but Man is a woman." Anyone who supplicates to others is broadcasting low value and will be treated accordingly. Consequently, the most supplicative member is often the one made scapegoat.
The converse paradox is also true: Those who display no fear of rejection are most likely to be accepted. While it might, on the surface, seem strange for people to accept someone who doesn't care all that much about their opinion of them, it actually makes sense at a deeper level because someone who has a fairly high opinion of himself, such that he doesn't care about others' opinions, will command respect by virtue of implicitly demanding it.
Thus, it is crucial to root out cowardice where it is found, particularly among young men. Men must have a healthy sense of self-respect in order to function in society, else they will be devolve into cowards. A man who cannot be confident in who he is or in what he believes is not really a man; he is a puppet to be used by those who prey on the weak.
* Perhaps this is why social ostracism, aka excommunication, is the primary form of church discipline. Perhaps this is also why God said it was not good for Man to be alone. Maybe God knows a thing or two about his creation.
** More accurately, words intended to make the listener feel bad exist more for the benefit of signaling to friends that you are fighting the good fight.
*** That is, by a spell.
^ I generally suspect that a lot of SJWs have daddy or mommy issues, or lived through a divorce or have been sexually abused. They strike me as miserably sad people who just want to belong to something and feel content, which is why I have a lot of pity for them.
