I mean I find reaction videos incredibly lame and annoying. I don't find them genuine, but rather super obnoxious. I also avoid them and never watch them. See no reason to shame and make fun of a dude for nerding out over shit. Whatever shit it is, anime, sports, games, cars, whatever I don't care.
But I do find the alt right battleground of masculinity extremely annoying and yes toxic. It's shit like that ladies post and what it really means that is pretty damaging to honestly society as a whole. I see nothing wrong with making fun of nerds. Being cruel to them is an entire other thing and usually conservative pundits lack the nuance to make that difference.
