However I did say a limit because, mainly pedophilia, which isn't really about two adults, but an adult and child(ren), whatever I feel about two adults doing what they want is different than a man getting a little girl into his bedroom.
also, yes the US was funded by Judeo-christians, but things have changed, and you go on about how "religion" has the right of marriage.

Being a GLBT falls under other opinion/other status
Universal Declaration of Human Rights wrote:
Article 16
Men and women of full age, without any limitation due to race, nationality or religion, have the right to marry and to found a family. They are entitled to equal rights as to marriage, during marriage and at its dissolution.
Marriage shall be entered into only with the free and full consent of the intending spouses.
The family is the natural and fundamental group unit of society and is entitled to protection by society and the State.
Following Article 2 of the UDHR, gay men fall under the Rights set out,falling under other status, and therefore the article 16 is connected to them, and since the US is not just a single nation, and is connected to NATO, the UN and various international organizations, it has accepted the UDHR in the UN, meaning that anywhere GLBT people have the rights to marry, according to the UDHR
