I got into a debate with my friend on this, me for and him against. And countered each and every one of his arguments, I'd like to think.
The definition of marriage is a man and a woman.
That largely depends on the dictionary. I checked about six or seven dictionaries, at least half of which either had gay marriage as an acceptable substitute, or the ONLY definition was between two people who loved each other, with NO mention of gender at all.
It's unnatural. Sex only works between a man and a woman, two men/two women can't reproduce.
It's very natural. Homosexuality is fairly common in both the human AND animal world. And if you wanna use the sex excuse, that's basically saying a marriage should revolve around sex. If you wanna think that, fine. But I doubt most people do think that.
The Bible says it's wrong.
This one was a bit controversial for me, being the religious guy I am. I don't wanna turn this into a religious debate, but I guarantee you 99% of the people who use this excuse have never even read that passage, or ANY of the Bible, that says that. Two main reasons why I say this:
1. The passage most people refer to says gay sex is wrong. It says nothing about gay marriage/love in general.
2. That same passage says "playing with the skin of a pig" (football?) and working or playing on Sunday are wrong. But we can still do that, right?
I personally believe the Bible was designed as a guideline for the time it was written. While it still should be used as a guideline for a Christian life, it is not a set in stone, follow this TO THE DOT. But that's just my feelings. Say I'm cherry-picking which of God's rules I wanna follow, and I'll tell you you're doing the same, Sir Holyer-Than-Thou.
Ironically, the friend I had this debate with, has stated multiple times he feels no connection to Christian, or any, religion, and has denounced any and all belief in God.
It ruins the sacredness of marriage.
See also: 99% of celebrity marriages, but we allow those.
Face it, for many, many people, marriage is hardly sacred nowadays. I like to think that it still is for me, and hope to never get divorced, but gay marriages do tend to last longer than many straight marriages.
Gays are freaks. They talk weird and dress like freaks, and just act freaky.
Stereotypes =/= Fact
I'm not racist, so PLEASE, PLEASE do not take this that way, but do all African Americans sit around eating KFC and not paying child support? Are all Chinese people good at math and video games? Do all Irish men get drunk until the floor spins round and round? No. It's a stereotype that represents a very minor percentage of a group, and could just as easily apply to any other group.
Damn, I've been outsmarted.
I really hope this didn't offend anybody, but these are just my views on the matter. I have gay friends, and I feel that a gay man has just as many rights as a straight man. Unfortunately for me, most of the people living in my area don't feel the same, so this is a view that labels me as a bit of an outcast. But just the same, I am 110% FOR gay rights.
