Against Gay Marriage = Against Homosexuality?

Then thank god I’m an atheist.

I don’t use the word “sin” very often, because the concept isn’t part of my belief system. But if a person is capable of sharing joy and bliss with another person, and yet chooses not to, the word “sin” comes to mind. Many people are celebate for many legitimate reasons, but to glorify chastity as a virtue is inhuman and inhumane.
