It's been my experience that if you read enough content online, you will realize that it's mostly people rediscovering old debates, and chiming in with what they think is new and insightful perspective which it usually isn't.
In a sense, I think the social sciences, philosophy, and the arts get "cranks" thinking they've figured them out, just like physics and math et c., do, except at a much higher volume, to the point that any discussion of those topics outside of highly specialized forums ends up consisting mostly of cranks arguing with one another, most of whom, if they have put any actual time into studying the topic at all, have fallen down some narrow crank-dominated rabbit hole of bad ideas. It's like if Flat Earthers were treated as having valid opinions.
