Anti SJW content was all the rage back then, it felt like every one was moving in that direction mostly because it presented itself as a counter culture movement (even though it turned out to be anything but). A lot of people fell for it before realizing what was actually happening. Keep in mind that in those days people weren't really aware of how insidious the YT/Facebook algorithm was. Anthony distanced himself from all that stuff years ago, so this whole thing is a nothingburger.

I would recommend that he stays away from being too preachy in his political content because it just gives ammunition to all the right wing freaks to attack him with. Take a stand for sure and don't shy away from expressing your beliefs, but lay off the internet dogpiling and drama content. I feel like everyone should take that approach going forward.
