"Same-sex couples and opposite sex couples are really different when it comes to the great reality on which marriage is founded which is: regulating the sexual relationships of the opposite sex so that they serve children and don't hurt them... So how does society do this? It's not because of what people do privately, it's not the wedding ceremony. It's the consensus around the idea that you gotta bring together the two great halves of humanity; male and female, to make and raise the next generation. If we had a powerful marriage culture, gay marriage would make no sense. Because the marriage culture is dramatically weakened, it's plausible to some people. But gay marriage institutionalizes the idea that marriage is just about romance." - Maggie Gallagher
This is the best short answer to the gay debate that I've heard and it is what I will use in my next post in the series to explain what children have to do with gay marriage. I'll post in the next week.. Stay tuned!
