You don't have a clue what goes on behind closed doors in any home. At least with adoption, you have to submit to background checks and home studies before you adopt and follow up visits afterwards.
Seriously, why do you have such hate in your heart? You seem to be a religious person. When you pray, is this where you believe God is leading you? If there is a God, do you honestly think he would rather children grow up without a family rather than going to a same sex couple?
We have 3 kids, one biological son and two adopted daughters. Both times we adopted, we adopted special needs from China. In both cases when we adopted, when we got our daughters they were malnourished. In fact, our oldest daughter was so emaciated and malnourished that I was buying her ice cream 3 times a day for the first 2 weeks we had her while we were still there in China so I could get some weight on her. They both had intestinal parasites, the oldest had ear infections in both ears so bad her ear drums had ruptured. Neither of them were getting any education. Our oldest was 9 when we adopted her and yet had no education at all. That was their life in a Chinese orphanage. Had they spent their entire childhood there, upon growing up they would have had little chance at life as no one over there hires uneducated orphans, or marries them, and they sure don't if they are special needs as well.
So when I think about how few families choose to adopt, I think that any family that chooses to adopt, regardless of whether its a traditional family or not, should be able to adopt if they meet the financial requirements, pass all the background checks, and pass their home studies. When we say to a same sex couple they cannot adopt, what we are also doing is quite possibly telling a kid that they would have adopted in some overseas orphanage that they don't get a family, they can spend their childhood uneducated, malnourished, with intestinal parasites, inadequate health care, and then when they are adults, they will have no place to go and little chance of ever finding work much less forming a family of their own.
I am serious when I say this, you should really look at what the world is like for these kids and what same sex families are like for them if they are adopted and then make a decision.
