Actually it's interesting to have this conversation bobbing in and out of the other one, as "the death of the SJW movements" or rather, what they could be, doesn't/didn't need to happen. Those "movements" made themselves the enemy, by pitching people that didn't share their preferences as the enemy. The "you have the right to a voice if your voice speaks as mine" attitude is rife in my opinion, and others were always destined to rise up against it. I think it being based on preferences and not principle is what sullies it, and what drags it away from a consistent logic that could be respected, even if not actually accepted, by the other side. Preferences vs principles? If one is not willing to extrapolate a proposed principle to it's logical end, without interruption, it remains topical and preferential.
A convenient hop, skip, jump, and sidestep around Islamic ways when otherwise trumpeting about female equality would be a common realisation of this. Of course "Freedom is having a gun, but don't be gay around my kids or I'll shoot you with it" hardly paints the other side as any better. Another example - people spouting about the "principle" of why video game violence is not a problem for society, then are all at sea when asked if paedophilia in a video game should be no issue. Gay marriage is "Yay!!" based on principle, but intrafamilial marriage is "Yuck, how dare you!!?". I could go on.
Back specifically to those under the SJW moniker - I think that what started out as a justified cull of wrongs saw people ultimately embrace the thrill of the hunt, and exhibit the behaviour of stirring up nests of "enemies" not to make a positive change, but to satiate their blood lust and have a figurative head to hang on their wall. Furthering the metaphor though sees them actually killing those that should deserve protection under their supposed justice mantra, and I think that inconsistency is the true "evil" in their actions.
