There are racist reasons for disliking hip-hop but disliking hip-hop is not inherently racist.
Yeah, basically this.
I don't really listen to hip-hop, but my lack of taste for that genre is a source of mild embarrassment rather than pride. I'm sure there's a lot of great art being produced there that I'm missing out on, but the world of arts and culture is just too big to get everything. At some point you just need to prioritize your favorite genres, and that shouldn't necessarily be taken as a slam against other forms.
Of course not. Is it racist to hate Tyler Perry movies?
For the record I've found that if a type of music is a target frequently and has a large Hatedom, it's a given that I hate it too (hip-hop, metal, country, pop and the garbage that 20RP12 likes).
You basically exclusively like a few incredibly specific types of post-punk music and you think everything else is garbage, right? That's not racist, you just have ridiculously idiosyncratic taste in music. You probably know why better than anyone else.
I would just say, maybe give non-post punk music a try. Maybe hip-hop isn't for you, but don't seem open-minded at all. And, if you're going to compare an entire genre to a single hack film director, you make yourself look like an idiot.
Correction: incredibly specific types of post-punk music, as well as
Blink-182, which is all sorts of hilarious. But yes, "open-minded" is not exactly in BRTD's vocabulary.
