There was probably a point where I couldn't differentiate, probably when I actually cared about fandom. But now I don't, so I couldn't care less what fans are like, in many cases I don't even know because I don't interact with them at all. However, it was less about hating on a band I already liked because of stupid fans, but more I would avoid bands with annoying fans.
in this case ignorance is bliss because I don't really interact with them now lol
