Why do religious people not approve of homosexuality?

[marshlander]

Religion is ran by men. God isn't, and all I've be told is the he/she just wants me to love him and accept him as lord and savior. Don't recall anything about listening to some guy telling what God should do and not do.

See that's where it begins to fall down for me. Who told you? What authority did they have for telling you what "God" wants? What evidence do you have that such a message genuinely came from "God" in the first place? What is the point of just loving him and accepting him as lord and saviour (and what does that mean anyway?)?

I could go on, but you're new so you're spared
