Am I Homophobic? Please read carefully and answer truthfully?

No, I don't in any stretch of the imagination think you are homophobic. I think your view of marriage is a little limited by your beliefs (what about straight people that can't/don't have children? What about lesbians that use sperm donors? Gay men that use surrogates? People that adopt?) but I don't think it's wrong or bigoted, I just don't agree with it, that's all. You sound perfectly reasonable and I don't see anything wrong with your attitude.
