This question applies to me. But the times that it bothers me most is when I ask someone, "do you like such and such?" and they reply with " I HATE that!" I take that personally because the word hate is so strong, and I feel that if people hate something that I love, by extension, they hate me.
I don't think I'm the only person like this. I often feel disappointed when someone criticizes or dislikes something that I love or appreciate. But we just need to remember that it's just taste.
The reason I bring this up today is the whole Harry Potter craze going on. I like the Harry Potter books; but I am better without them. They really have a negative effect on me. But that doesn't mean that I disrespect people who like it.
Anyway, I feel this is a valid question.
