I look at the gay condition as an out of control obsession, just like alcoholism and drug addiction. There is ample proof that alcoholism is inborn and that some people simply cannot drink without it becoming a problem. They have a choice to either follow their "natural' instinct of drinking themselves into oblivion, or give it up and totally abstain. I don't think any sane person would suggest that they just "enjoy' drinking when they know that doing so is destructive.
There are some people who have a pre-disposition to serial killing. It seems that certain personalities have a "natural' desire to kill. No one would suggest that they go out and fulfill their "natural' desires.
There are certain primitive cultures that engage in man boy sex and view it as a normal right of passage to adulthood. Does this make it right? I dare to say the vast majority, both gay and straight would view this as disturbing.
So here we have someone who has a pre-disposition to gayness. It seems to be true that certain personalities are naturally attracted to their own sex. So maybe it is natural, but it is certainly not normal, and to encourage gay marriage is an attempt to change societies views on gays and make them feel normal and accepted. I'm not suggesting we bash gays, but those that believe there is something wrong need to voice it loud and clearly, so that their children are not confused on the issue. I believe there will be children that may be on the fence on this issue, and could be pushed either way, depending on societies views. If society views gay as normal, those impressionable children will be swayed to the darker side. Gay marriage only makes it seem more normal. Sex with children animals and etc will be accepted as "natural' eventually, given time.
The bottom line is, we need to draw a line in the sand and say enough is enough. Not all human behavior is acceptable in an organized society, and their needs to be limits set, or society will ultimately disintegrate.
Based on the changing lax attitudes towards gays in this country, is it any wonder the Bin Ladens of the world want to attack us? You can't turn on the TV anymore without seeing some show about gays. Right now it is usually in a joking manner, but give it time. Do I hate gays? No, but I don't want them flaunting it front of my impressionable children either.
