I am opposed to gay marriage, and especially allowing them to have children. It seems to me that homosexuality is a disease. If you allow these sick people to raise children they will grow up the same sick people.
Homosexuality exists since life exist and all animal species experience homosexuality, don't make me bring my biologist brother to argue. Also, with that argument, are all fetishes diseases?
In my opinion, I have nothing against homosexuality, their marriage or adopting children. Homosexuality is a natural thing, there's nothing wrong with it, marriage should be permited to everyone who wants to seal their relationship and love and about those adoptions, well I'd rather have a child grow up in a loving and caring family that can give them a comfortable life than growing up in a foster family or some center for children without parents.
