If America and Europe were a test on the effects of gay marriage on society, I think it's fair that every other country bans it.

What you do in your own home is your own business. But normalizing/promoting the sexual deviancy of a minor part of population is not healthy for society. The slippery slop is real. Make whatever private contracts you want with the person you love, but I'm done with marriage. I use to support it, I've changed my mind, it was a mistake.
