Someone says they like hip hop, and you imagine a young urban male with a baseball cap on backwards, how they view women, that they probably don't like musicals, something like that (not saying you do, but as an example). More than simply the thing they said. You say "I like or do that thing", and instantly get hit with "oh, people like you always complain about X but isn't it weird you never mention Y".

At least that's what I thought of when I read that; because answering in place of other people is another thing I find annoying. So I'm speaking for myself, but with some optimism I may have guessed the intent of OP correctly :)
