What haters of an artist you like annoys you the most?

There's normally always a reason to hate a band, but personally I can't stand a lot of Deathcore haters. I'm not gonna defend this genre to death, but the ones who think it's all emo fringes and breakdowns don't actually do proper research. Yeah, there are some bands that actually do live up to the general stereotype, there's no use in denying that. But not every band is what the genre is generally thought to be. I don't think Deathcore is by any means reinventing anything, but like I said a lot of it's haters could do some research.
