I hear you. I grew up in a Christian household, and when I was a child my aunt took me to an anti gay marriage rally (before it was legalized in Ontario in 2003, and later on the whole country in 2005).
I remember someone from the news asking my aunt why she was at the rally today, and her answer was the typical Christian one: "I just don't believe it's natural and God is against it. Man should be with woman." Even at that young age, I remember thinking how stupid of a reason that was.
These days I rarely see homophobia, it is very much frowned upon. Fortunately where I live, those who are against it tend to keep those opinions to themselves or within their religious groups.
