I'm not offended easily, but I know a few people who are and they get on my nerves because it's impossible to have a conversation with them without them getting offended over something that comes up. In my humble opinion, these people need to grow thicker skin because in the real world nobody cares about the genders sexualities of fictional characters.
Racial terms...Ehhh. I don't use them because from my experience they're the kind of words that you can't just say on a whim. Everyone I knew in high school who used racial terms had grown up around racist people. Hell, my brother's a huge racist and it's because he grew up with racist friends who had racist families and other racist friends.
I absolutely do not care about other offensive terms.
