[A supposedly secular fundie ... you be the judge.]
I do not believe in the concept of "sin" and "God", but I strongly believe that homosexuality is against the laws of nature, and against societal norms...and is therefor immoral according to the dictionary definition of the word immoral.
The thing that erks me the most is that homosexuals will give the "it's genetic" argument, when in fact there is no hard proof that DNA is responsible for homosexual behavior. You know you're gay when you're little? Please. Your endocrine system isn't even developed at the times some people claim to have known when they were gay. It is a psychological abnormality stemmed from one of two things (or both):
1. Sexual abuse of the child in question, or abuse of the parent of the same sex by the parent/partner of the opposite sex, giving subconcious negative feelings toward the opposite sex...and/or...
2. A purely lust-filled narcissistic obsession with one's own gender role and appearance.
It also makes no sense to parade around for "rights". This is America. They are in possession of all rights other people have by birth in this country. They don't want rights. They want special treatment.
