For those who are anti-religious in this debate here are some articles that take on "what difference does it make.." argument from a purely scientific (?), demographic (?) argument that is now just starting to show itself...

And what does Kurtz think happens when gay marriage is passed...
From Mr. Kurtz's article, "Unhealthy-Half-Truths."

And the important part...
So yes, there may actually be a bad outcome, non-religously based for those who are anti-religious, that may occur with the passage of gay marriage. Now, with an actual non-religious argument, can those calling the religious people out there bigots please refrain. They may have a sense of something that they can't explain, but just sense from real world experience with out of wedlock children who fair worse in society than those children who are in two parent homes. And yes, gay couples are two parents, but it seems there may be evidence that not equating marriage strictly to child bearing may have a bearing on out of wedlock birth rates. Read both articles and see for yourselves...
Yeah, you may think this is hogwash, but this is an argument that should be looked at, as the consequences to the individual children are devestating and the consequences to the society even worse. Worried about extremist ideologies, where do you think they will find their future adherents, the less successful, socially isolated, children born out of wedlock. Like street gangs, where do you think their recruiting prospects come from, out of multi-generational out of wedlock children. This is where you get 13 year olds who can kill without remorse, just ask any big city cop.
So there...
Because in contrast, the US does not have out of wedlock children, single parent home, kids having kids, etc...
Yet another BC link that is pure horses**t.
