I don't get it. Like saying gays invented heterosexual marriage? Go Proud yourself somewhere other than FR.
It's true, though, that you're not comprehending what I said. I said heterosexuals had already largely redefined marriage by accepting premarital sex, divorce/remarriage, contraception, and the rest, so that marriage was neither exclusive, nor faithful, nor durable, nor fertile.
This is sin.
The gays now find that redefined, de-sanctified, sterile marriage suits them to a T. That's even more sin.
Sin is damnable stuff. Nothing to be proud of.
