Maine Senate Backs Same-Sex Marriage

Okay. Same sex marriage has been a hot topic for some time now. The article Maine Senate Backs Same-Sex Marriage basically states Main has legalized same sex marriage. Although I am completely straight, and not for same sex relationships. I think that all humans have the right of speech, to vote, the right to have weapons, religion etc. so why shouldn't they have the freedom to marry who they want. I am a strong Christian, but I do not have judgement upon them. Everyone has there own thoughts, believes, culture and so forth. So if they have a religion, they know you will go to hell for marring the same sex. Therefore if they want to spend all eternity in hell...that's their decision..right?
