One unrelated to the other as the question was about the effect of gay marriage on society.

It is a biological fact that being exclusively gay takes you out of the breeding pool. Whatever limited effect on the population does not change this as a biological fact. In context if violates one of the primary historical and cultural reasons for marriage. BTW hetrosexuals that do not have kids pay a tax penalty so there is even an economic reason to have kids.

Bottom line the majority of Americans feel gay marriage should be banned. They do not have to give a reason they can just vote. Now if the gay lobby wants to use the legislature to propose a law or an amendment allowing gay marriage they are free to do such. It will never pass. Using the courts to destroy our system of government and right ot self rule to force acceptance of gay marriage is wrong and un American.
