Marked vs. Unmarked

One occasion when i noticed that I was marked was my senior year of highschool. It was the end of the year so we were just in class talking about random stuff. Someone brought up the topic of favorite musical artists. I said "I like Alecia Keys" and people in the class started to look at me funny and make remarks like 'ewww' and roll their eyes. A girl in class was like "tania, thats enough" and I was confused like what was going on because no one elses comments ellicited such responses. I realized that they must have thought i meant that i 'liked liked' Alecia Keys, and that i was attracted to her. For a second i began to feel stupid, i felt like i should have remembered that I am a lesbain and because of that, i need to make it clear that im not a sexual predator and that my remarks were strictly relating to her music. but then i realized that i did nothing wrong but forget that i am 'different' and for some reason, the general rules of conversation dont apply to me. needless to say i was offended
