My point was that I don't think any fandom is worse
cringy and intolerable people exist in general, a fandom just gives them something for their awkwardness to manifest through; to make them stand out more
and then some general distaste for a group, combined with some confirmation bias, you start believing that x group has more awkward people than y group
Even if the annoying members of a fandom are the minority you can still find the fandom as a whole intolerable because of their presence within it. That's not the fault of the fandom as a whole, and it's not fair, but life's not fair. It's still possible to dislike a fandom because of a minority within it, because it's often the case that when that fandom pops in so too will the annoying minority and the actions they perform.
It eventually becomes very difficult for an outsider to distinguish between the fandom and it's unruly/loud/annoying minority.
Bitching about the fandom as a whole because of that minority isn't nice, but wanting to avoid the fandom in order to avoid the minority is an acceptable opinion.
And it's still possible to argue which minority of which fandom is the most annoying to you, because often those minorities are annoying in different ways.
