I fail to see how her being in a sex tape relates at all to her opinions on gay marriage. While I don't agree with her views at all, I think she has every right in the world to have them. I also got tired of hearing her whine on the news that she didn't win solely because of her views on gay marriage. I don't believe that for a second.
The question was asked of her by Perez Hilton who used it as a way to grandstand because he's an attention whoring douche. Now she's got a sex tape and a fair amount of people on the left are cheering. Why? Because they want to see her brought down a peg for daring to have an opinion on gay marriage that they don't agree with. It has nothing to do with her being a hypocrite.
Guess what? People have a sex life. Some people film it and get into some pretty kinky stuff. How does that in any way invalidate her opinions on gay marriage?
People get pissy because they think she promotes this family values image, but that's bs as well. She was asked a question and gave her honest opinion on the subject. It's not like she went out of her way to give her opinion by trying to shove it down people's throats. This is nothing more than people on the left lashing out because someone dared to have a differing opinion on an issue. So, of course, they like to see that person humiliated a bit.
