We earnestly and aggressively need to stop letting Christians monopolize conversations around the definition of marriage, you know that thing that cultures all over the world do?
"Marriage is a Christian ceremony." No. It's really not. There are cultures all over the world that practice it and there is a political and civil definition outside of that. You're just boring, insulated, and likely not invited to these things for a reason
Shocker for a culture defined by taking and forced assimilation, this isn't about you or your god. At least not in a way that matters. It's more about allowing biracial families raise their kids or allowing someone see their SO in the hospital.
