I said "GAYYYYY" when my son came out to me
Don't you care how that effects him?
Not really. I don't like him anymore
That's terrible of you to say! You shouldn't judge someone, especially a family member who you're supposed to care about, over their sexual orientation. Learn to be more accepting!
I just want to forget about it and get on with my life.
There's nothing wrong in being gay. So you should be supportive to your son.
