Hi Avacadotoast,
It's not at all weird for someone to dislike porn, just like it's not at all weird for someone to like it. People feel all sorts of ways about porn based on things like their beliefs, sexual preferences, and so on. Too, porn encompasses a HUGE range of things, so while a person may be disgusted by one type of porn, they may discover another that they really enjoy.
As for why some people like the kind of porn that disgusts you, it's the same reason some people like horror movies while others don't, or like oral sex while others don't; people have different likes and dislikes, ones that have been shaped by all sorts of things in their lives. So what turns one person on may be really offputting to another. Does that all make sense?
If you're curious, these articles do a really good job of helping people make sense of porn and other sexual media:
