"I don't believe God exists. Why should I take the moral system of something that has no evidence for its existence?"
The part of you that requires scientific evidence in order to observe its existence will have to be altered in-order for you to have faith. That alteration is not something that I can do.
"If you want to use that as your personal moral guide, fine, but you cannot force it on others....."
Ya, I can; at least in so far as any law could be "forced" on any citizen. It's called "voting". In fact, the entire purpose voting is so that individual citizens can have a say as to what should and should not be allowed. Since the "why" is not recorded, I can have any "why" that I please.
"....because it's not universalizable"
While religion is not, the Creator, its self, is.
It's a matter of personal faith and understanding.
"You must believe in the deity."
Too oppose gay 'marriage? No.
If I had a purely economic reasoning, then I mite oppose gay 'marriage based on that. There is no religious or theological requirement for opposition to any given piece of legislation. That's the beauty of voting: *why* is not recorded. Only "yes" or "no".
"I shouldn't have to follow your god's rules any more than you ought to have to follow Shinto morality."
Then don't.
"Everyone thinks his God is real and his neighbor's false."
You're leaving out another approach: Everyone knows the same God, but they view Him and understand Him in very different ways. For example: Jewdeo-Christianity and Islam both worship the same God, but to look at it today, you would never know it.
"The difference is that crack babies are mentally deficient and unhealthy; homosexuals can lead very healthy lives, and many of them are extremely intelligent, productive members of society. Furthermore, most crackbabies are "created" via improper, criminal conduct. Homosexuals aren't."
I am aware of the world of differences between the two. That's why I said "very general commonality".
"Playing Hockey also wastes time that could be put to better use somewhere else. It's a diversion. People should be working, not playing. If people worked more and played less, more would get done."
From the Contractors who build and maintain the coliseums and the financially benefiting transportation, catering and lodging businesses, to the advertisers of products of which the fans perchis at your local department or retail store (to say nothing of the additional payrole that said store could use to employ more people when their sales are up), I hate to say it (because I hate sports) but commercial Hockey is good for the economy because it produces Jobs.
Without it, fewer people would have work and less would get don.
"Still, why does the "attraction" of mates equate to morality?"
Don't change the subject. We're discussing rather or not to support gay 'marriage legislation, not making moral judgments about why people are attracted to whom they are so inclined to be.
"Since Homosexuals make up an extremely small global population, there is no reason to fear that "homosexuals" will make reproduction of the race impossible"
Fear, being a morally based emotion, I did not mention.
Likewise, reproductive abilities of the Human race, I made no issue of.
"Why? First, there is zero evidence homosexuality is learned as a practice. You cannot "create" new homosexuals other than by having them biologically. Whether or not you allow them to marry has zero impact on the production of new homosexuals. Therefore, the argument from Population need has no merit."
Agreed. The population argument has no merit.
"If they marry, nothing happens to the population.
If they don't marry, nothing happens to the population."
The path of hypocrisy would, indeed, do something to the population....but you will have to open your self to faith in order to accept an example.
"Homosexuals will always exist..."
Yes. That is just a fact of life. There is no denying it.
"...unless you propose we exterminate them all because they are a drain on society."
I'm sorry, did you read something about Army-of-God in my profile or something.
A sinner I am. A Nazi I am Not.
