Yeah well, the problem is that the sources in most wikipedia articles aren't academic level at all.
For example, the one linked earlier for SJW has "The Guardian" as a source. You should agree that's laughtable.

It's laughtable and suffers from recentism. If wikipedia would abide their own rules they would throw away all those "trendy" topics until the event is far enough that proper studies could be made... but they wouldn't get sweet and juicy donation money without that stuff.
Politics there is basically the clickbaity stuff which earns the dosh.
