I'm going to refuse to be my little brother's support/back-up when he comes out to our homophobic parents
Why wouldn't you backup your brother?
I don't accept gay people in my life yet.
I think not being accepting of gay people is just wrong. You shouldn't have an issue with anyone's sexuality.
Being gay is a choice. He's going to regret it.
Being gay is not a choice, it's just who they are attracted to. You should be more understanding towards gay people and your own brother.
