This really doesn't surprise me that much. The well-off conservatives that rant about SJWs area easy to understand, and having lived in the Bay Area a while, there's also a large population of well off leftists that seem to live in a bubble where Trump isn't too far off from Hitler and Fascism is apparently a mainstream political view. Despite that, most of them would condemn the actions by "SJWs" you see in your typical "SJW owned video".
The right is ranting about a left that doesn't tolerate controversial opinions that exists, but isn't nearly as widespread as the right would like to believe. The left rants about a right that advocates for white supremacy and the purifying force of violence that technically exists, but isn't nearly as widespread as the left would like to believe.
It seems like we have a fake problem created by people with too much time on their hands.
This is lolbrooksian false equivalence served up with statistics. I don't think that the "radical left" came to the conclusion that America ought to have a single payer system because they're part of a "cult." While there sure is tribalism, it's patronizing to equate Trump and his ilk with modal far left voting group.
What problem, precisely, is fake?
