Tell me about it. I have some additional points, if you don't mind. Sorry if I'm a bit redundant. You are absolutely right.
Let's break this down like rational adults.
1. Gay marriage doesn't hurt anyone. If you don't like gay marriage, don't have one.
2. There are hundreds of documented cases of gay animals. Just because someone doesn't bother to study biology doesn't mean they can claim it doesn't exist. As for those who say animals are disgusting, they are much less cruel and vicious than humans. Most animals don't kill for fun. Those who kill for food don't keep their prey locked in a cage, wounded and suffering and being tortured their whole lives. Watch the video "meet your meat," then tell me that humans are more decent and pure than animals.
3. Procreation - Yes, the world isn't overcrowded enough. By all means let children rot away in orphanages, because dammit, we need to kick out more babies! The Earth isn't overpopulated enough!
4. Procreation - only people who can have children together have the right to get married - so old people and the infertile don't have that right, either?
5. Raising children- Hundreds of psychological studies have conclusively found that the only difference between kids raised in gay homes and in straight ones is that the kids in gay homes tend to be nicer to people who aren't just like them. Less racism, sexism, religious intolerance, etc. How horrible!
6. Marriage is a legal document. Unless you chose to have a ceremony in a church, it has nothing to do with religion.
7. The Constitution clearly states that there cannot be one religion elevated over all others (that's why our forefathers came here, duh). Because many religions celebrate gay unions, OUR religious rights are being violated by banning them. Oh, right, we're inferior to Christians, huh?
8. Even if it were a choice (yeah, every single gay/bi person in the world is lying about that *eye roll*), so what? Religion is a choice. So we can forbid you to build churches, right? After all, you CHOSE to be Christian.
9. Adam and Eve both had brown eyes. So anyone with blue eyes is an abomination, right?
10. Since your god said that when a man takes a wife they should be as one. The omission of any mention of staying single and gay relationships, they are automatically forbidden. Anything not mentioned in the Bible is automatically bad.
11. Jesus made it clear that instead of doing unto others, we should force everyone to live by Christian laws even if they aren't Christian.
12. God said eating shellfish is an abomination too, but he didn't mean that one, really.
13. The Bible is obviously the best moral guide a person can have. After all, it tells you all the proper ways to have slaves, instructs you to set up a fair price when selling your daughter into slavery, and it's always very reasonable about the specific ways we should stone our disobedient children.
14. Gay marriage hurts all other marriages. You'll wake up in the middle of the night and say "Oh no! Two men just married each other in another time zone! Our marriage is less valuable now!"
15. Gays can't have love, only lust. All those 90 year olds who have been together 50+ years and look like they would snap like a twig if they had sex are obviously together only for lust.
16. It's just like any other sin. Should we allow murder or the rape of children? Because of course murder and rape do the same amount of harm as being gay.
17. Other countries have permitted gay marriage and are doing just fine. But we're different. We'll collapse and be ruined.
18. People will marry dogs. Because a dog is recognized as a human being and can consent to marriage and sex. Dogs and gay people are about the same level.
19. The "I find it gross" argument is perfectly valid. I find dogs gross and disgusting. I think I'll ban dog ownership.
20. Churches will be forced to marry gays. Sure they have the right to turn anyone away for their religion, divorce, race, refusing counseling, having tattoos etc., but they'll be forced to marry gays.
Again IT DOESN'T HURT ANYONE!
Can anyone dispute these arguments? It's impossible.
"I think almost all religions are against homosexuality" This is not true. It's just that most people have never even heard of more than three religions. There are 10,000 in the world and most are less bigoted and have no concept of hell anyway.
As for the city that was supposedly destroyed for homosexuality, maybe these guys should actually read their damn Bible instead of using it as a weapon:
"Behold, this was the iniquity of thy sister Sodom, pride, fulness of bread, and abundance of idleness was in her and in her daughters, neither did she strengthen the hand of the poor and needy." Ezekiel 16:49
