Somehow its always SJWs.
@Jaimas, why is it almost always SJWs that wind up causing niche communities to turn into actual drama hellscapes of everlasting reee?
The same reason it always is, my good Darkmage:
Firstly, most of the people who wind up becoming the worst offenders have infinite free time, are not gainfully employed, and have no lives outside of social media. Those traits alone do not translate, necessarily, to a community of shrieking degenerates, but they basically set the stage. It also means that once the problem metastasizes these people have nothing but time to throw at whatever insane causes they choose to champion.
That brings us to the second reason: Tumblr in particular is such a shithole of identity politics and psychiatric problems is because of the culture that the above curates. This curation comes about heavily because of a big push by post-modernist ideologues and assholes pushing the usual talking points: Normalcy should not exist, moderation should not exist, deviancy is good, logic should take a back seat to feelings. Because many of Tumblr's users fall into the above categories (NEETs, nothing but free time, etc), they're easily swayed by easy answers and due to
how the Tumblr definition of privilege works, they wind up going all in because it means embracing a worldview where nothing bad is ever your fault.
Finally that brings us to the third reason: The ideology at the core of Social Justice - Intersectionality - is driven to take over everything it can. Its ideology means everything that can be co-opted must be; indifference is not allowed, opting out is not allowed, and escapism cannot be tolerated. There is no such thing as something that
isn't political in their worldview, so everything must be part of the same tired refrain,
or else.
The end result is that a bunch of NEETs with unlimited free time and have opted into an ideology that gives them nothing but positive reinforcement and encourages them to be assholes (and also to take over every platform they can).
