I think what bothers me most about people who use the “slippery slope” argument against gay marriage is they always say it’ll lead to people marrying dogs or cars.
Thing is, I find the underlying mindset disturbing more than the fact they’re making the argument. Cars aren’t alive. Dogs are incapable of providing informed consent. Neither are legally resposible for themselves, recognised as sovereign entities. The underlying mindset seems to be that marriage is something that you do to others, wether consentual or not. It seems to cry “I beleive marriage is an act of violence” first, arguably worse than the explicit text that they only beleive it should be commited against the opposite sex.
Or given the context, perhaps that should be the opposing sex.
It screams, “When I marry someone, they are my property”. My object. My slave. My Husband. My wife. My dog. My Car. Mine.
Maybe it’s actually the frequent use of the word “partner” they object to.
