I’m not a particularly religious person, although I believe in God and that God came to earth as Jesus. I do not follow the church but I do believe in the bible. For me personally, this issue isn’t about religion. I find homosexuality repulsive on a visceral level. I find it unnatural, abnormal, and in the case of men......filthy and unhealthy. The anus is colonized by e-coli and there is no getting rid of it short of administering certain antibiotics such as those used for certain surgeries and at that, it is temporary. There is no way to permanently rid that area of e-coli and that bacteria in the urethra causes infection which is why gay men have chronic UTIs. That’s not even to go into STDs like AIDS. Lots of non religious people have a natural aversion to male homosexuality for these types of reasons.
So your opposition to same-sex marriage is based on your own “visceral” reaction to homosexuality in general? Interesting. I think many people, maybe even most, object for the same reasons you do. It’s rare to find it so frankly stated, though.
