The fundamental premise that supports same sex couples is that men and women are 100% interchangeable. That premise is also associated with feminism. That premise is false and easily proven so by common sense.
Sexual union between same sex couples can only be achieved by means of acts of sexual perversion with its attend risks of sexually transmitted disease, mental health problems, and exposure of risks to the general public. Public health and elected officials, if they were doing their jobs, would forbid same sex marriage because it comprises the health and safety of the people they have sworn to protect. It is that simple.
The most devastating campaigns for the deconstruction of the institution of marriage were carried out by heterosexuals... The homosexuals are simply scavenging on the ruins.
It was a decayed heterosexual society that broke down the "definition of marriage" so that it was temporary, serial, and sterile. At that point, it was exactly what gays were looking for: the gratification of adults, with all else being optional.
In particular: contracepting couples have already turned sex into an infertile-by-design, mutual-pleasuring "unnatural act." They are heterosexual gays.
