I'm sorry that your pain has brought you to a place that has you advocating a position that is guaranteed to cause more pain to other children. You must know that children will continue to be raised by same-sex couples. Gay marriage doesn't deny children anything. It grants them equality.
I grew up a straight girl in a gay world, the opposite of what most gay people experience, but with the same problems of lack of place. I didn't feel that I made sense in the heterosexual world either.
Opponents of same-sex marriage in Utah and Michigan maintain that children of same-sex couples do not fare as well as those raised by married heterosexuals. This would be laughable if it did not have the potential to cause even further damage to children like me.
