Yes, I get it. You’re going back to the same argument made by every group throughout American history. If we let in those damned (Irish, Jews, Chinese, free blacks, Italians, Muslims, Catholics, Hindus, Faroe Islanders, Lichtensteinians, three-handed Martians) they’ll complete with us for jobs and jobs must be reserved for us (Irish, Jews, Chinese, free blacks, Italians, Muslims, Catholics, Hindus, Faroe Islanders, Lichtensteinians, three-handed Martians) who were already here.
That’s an argument bitterly fought out for centuries. The exclusionary side has always lost the argument in time. The argument itself looks stupid in the rear-view mirror. (No Irish or dogs? What could they possibly have been thinking?) Admitting these others into full acceptance in society has always given far more to the total wealth of the nation than was lost by individuals. (Making only moves in which no individual ever loses is not a rational argument. No such moves, including doing nothing, exist.)
The argument that groups should not be treated equally is a selfish and fundamentally bigoted one. No married person has lost anything at all by the recent cultural shift which allowed gay marriage, despite the decades of screaming lies that doing so would destroy their traditions. You can substitute any other form of current inequality for gay marriage and the outcome will be the same.
Oh, and we’re not asking evil conservatives to grant anything. We’ll be taking control of society and forcing you to live in disgrace for your bigoted beliefs, just as has happened with gay marriage.
