Rick lacks the moral imagination to understand just how deeply offensive it is to not only gays, but so many others, to conflate polygamy and allowing one man to marry one other man. I am going to give him the benefit of the doubt that despite what he says about the two concepts being essentially fungible, he is not so obtuse as to not understand that he is comparing apples to oranges (well that is putting it charitably, it is more like conflating apples with tupperware).
It is one thing to make attenuated arguments based on zero empirical evidence that legalized gay marriage over time, might undermine the family unit. It is quite another to segue off into comparing two men getting hitched to each other to beastiality and legalizing a man getting a second or third wife, when the first one has had too many miles put on her, creating a shortage of eligible woman (probably leading to more gay sex to boot.
). The latter is what Rick does without the slightest bit of personal embarrassment.
One of the reasons Rick would make a lousy and potentially dangerous POTUS, is that he tends to have a Manichean view of the world. That is
not good.
