All the fucking time. My mom sometimes makes comments about how being gay isn't right, even though I know she doesn't mean to offend thats just how she was brought up. She treats me the same she just doesn't like it, but she doesn't hold it against me.
My brother on the other hand constantly makes fun of gays, saying its wrong, they're corrupting the children (Even though he and his wife are in a loveless marriage and they've both cheated on eachother multiple times, and he has the nerve to comment on the sanctity of marriage,) etc. He's a Fox News watchings extreme Republican. His hatred of anyone or anything different (He's a bigot) pretty much has estranged me from him as I choose not to talk to him, even though I'm not out to him. The worst part is that he says all this shit to me even though I'm sure he suspects...so its particularly hurtful. You just have to deal with it, I know its not fun but you can find yourself a support group and a family outside of your family that accepts you for who you are.
