I can't answer for OP but I will answer for myself.

Profanity I don't have an issue with. Kids are going to hear it, it's not an intimate act. Violence..our country is constantly at war with someone, how can I hide it from them?

Hetero sex scenes..I don't have an issue with in general. It's natural. Most of us eventually do it. Pornography I have an issue with and my 6 yr old isn't watching Skinemax so he doesn't see graphic portrayals of sex. He also watches DVD's on my laptop about 99% of the time so again tv isn't much of an issue.

2 men engaging in sex, for example, on television and my child seeing it, I don't approve of. Again, it's unnatural and my child doesn't need to be asking questions about it at his age. "Yes son, what happens is that when two men are in love one gets on his hands and knees and readies for his partner to penetrate his ass".

See with a man and a woman and natural, normal love making the answers come easier. His penis was made to fit into her vagina. I don't have to go into details about oral sex or other forms of sexual stimulation gays use to work around the missing orifice/appendage. I don't have to explain that the hole to penetrate in male gay couples is the one where poop comes out. I don't have to explain that two women can't achieve penetration without buying dildos or that one woman has to eat the other one out. See, my son is 6..he needn't know what couples do period but when he comes to me and asks I don't want to have to give him graphic details of how the abnormal couple has to have sex to achieve what comes so easily for a man and a woman.
