I don't want to hang out with my friend anymore after he came out as gay
Do you not like him because he is gay?
Yes, I don't want to be around fags. I hate fags.
That is awful. You should be there for your friend. You shouldn't abandon him just because he is gay.
I'm living in a hetero world, so I need to be around my own kind.
You shouldn't discriminate gay people so much. What does it matter who they are attracted to? You should learn to accept them no matter what.
