I am not gay, but I am 100% for gays to live whatever life, in whatever legal arrangement they would like.
I am also 100% for every gay person to be able to adopt, if they so please.
After having many gay friends, I know for a fact, they are no different that anyone else. They just don't happen to like sex, straight up. Their prerogative.
I know, in my heart, that gay people will have all the freedoms they desire within the next 20 years. And I wish them the best of luck, and will support them anyway I can.
