2%? That’s where you’re wrong. A majority of Americans now support sexual immorality. Or, if not a majority, all too many.
It’s difficult to embrace your own sexual immorality and then stand against another form.
Therefore the majority of heterosexual couples are perfectly comfortable with an altered, aberrant form of sexuality--- one which is split off from fertility --- as their right.
Naturally they would be allies of gays who want the same.
In effect, it was contraceptors who queered marriage. It's not remotely surprising that gays want to opt in. It's custom made for them.
