Why not dub these homosexual unions as Freak Shows? So what if it sounds harsh. Calling their actions unnatural obviously hasn't affected them or some seemingly conscience-less judges. They don't give a damn when they usurp real marriages but we don't have to agree with or accept their destructive agenda.
I've long believed that many heteros have given ammunition to the homos due to adultery, babies born out of wedlock, the huge number of divorces, and the harm brought on so many children. Still, that doesn't excuse the behavior and demands of homosexual activists.
For now I will call these unions Freak Shows.
You’ve identified the big picture - the agenda to destroy the family. That includes divorce, adultery, pornography, abortion, homosexuality, and promiscuous use of birth control.
