Not the person you’re replying to, but I think it’s reasonable to dislike a genre when one dislikes the things that define the genre.

I don’t like death metal because I find the vocal affectation silly and the range of instrumentation too narrow. I dislike country for exactly the same reasons.

There are genre-defying artists who transcend the category; Patsy Cline comes to mind.

But if someone’s going to sit down and write a song that conforms to all of a genre’s conventions, people who dislike those conventions probably won’t like it.
