In response to MH,
I am not sure if I agree with your logic. I am a Christian who is married to the opposite sex. You say:"God or evolution made you gay, so you will not reproduce" I cannot reproduce either because a variety of reasons, now does that mean I should not have the right to adopt a child?
You say: "For a child to grow up, especially the teen-age years, with same sex parents would be confusing and would lead one to think that gay is as normal as being straight" Children grow up all the time with less then "normal" circumstances and things turn out fine. With your logic it could also go like this: The bible says that divorce is wrong, children grow up with divorced parents would be confused and could lead to them thinking that divorce should be as normal as being married and working through your differences. I grew up in a divorced house hold. A situation that was less then normal. Did I grow up thinking that divorce is normal?? No I didn't. I see divorce in regards to my parents for what it was. Giving up instead of working on their marriage. Am I confused on the issue? No, I am doing what ever I can to strengthen my marriage so that does not happen. Like I said before, children grow up with less then normal circumstances all the time, just like me and I am not confused at all.
I see no benefit to not allowing gay parents to adopt a child. They should be allowed to adopt.
