Thomas Sowell goes deeply into the psychology of the sjw in his book The Vision of the Anointed. His view of them is ours stated clearly and with references. If not quite a religion, there is definitely a typical belief system and relationship with others (They being the Anointed and the others being the Benighted or the mascots). Sadly he sees this as a self-reinforcing and self-rewarding coping system which hardens into unchangeable because they will not accept empirical evidence that contradicts the axioms of their beliefs. In this way they truly are mentally ill, in the basic definition I grew up with: they are not operating in the "real" world of most people who can adjust to reality as they see their assumptions are incorrect. So it seems to me a real test of the whole conception would be to find the right therapeutic approach. Lately there are many anecdotes of cures due to the shock of seeing beliefs put into action.
