There's no such thing as gay marriage anyway. Marriage is a religious sacrament where a man and a woman swear an oath to the death to each other in the presence of God. Anything done outside the Church is at best a civil union, but not a true marriage. The secular world has stolen the word "marriage" and think they can make up their own rules for it. But that is not true. And, of course, the mentally ill shouldn't be able to adopt. The children need to be placed in a normal family with good father and mother role models.
