“I can’t wait for the first gay divorce. If you think normal people beat each other up badly in divorce cases, think again.”
It’s already happened. Of course, gay divorce is no more (and no less) an argument against gay marriage than straight divorce is an argument against straight marriage.
“Anybody notice how every religion is very consistent about marriage being between a man and a woman?”
There are churches which perform gay marriages. And of course, there are (and have long been) religions which recognize “one man, multiple women,” “one woman, multiple men,” “one old man, one little girl,” and St. Paul himself felt that marriage was nothing more than a “necessary evil” for those who didn’t have the fortitude to hack celibacy.
