I'm going to tell a gay person that I felt uncomfortable around them in front of my whole class
What made you feel so uncomfortable around a gay person?
Every time i'm with that kind of people it makes me uneasy
I think that this is something that can be done in private. It is wrong to publically embarrass someone.
It's not publically embarrassing, I'm just informing them. I'm sure he won't act gay.
It would be embarrassing though for you, you are stating nothing but how awkward you felt around someone for no reason. Being gay isn't a good enough reason to not like someone. Unless there is a valid reason, let them be and try to get along.
