Pour Decision Maker
I agree. But that's not the issue, it's the explicit formulation: "I only date X race".
The problem comes when you enact a personal Jim Crow, draw a line and say "I only date people who meet X racial requirements". That's racism, that is an explicit policy of racial discrimination, and that's a choice that somebody makes and can therefore be held accountable for.
I only presume people are racist if they actually say a racist thing. If someone is a closet racist, I have no way to know.
It is only racist if they say it.
So if they make up an lie and say "I wouldn't date you because I am still getting over my last relationship," or if they just don't call you then it isn't racist.
Giving voice to one's preferences makes suddenly changes the equation.
