None of those website look like WS to me, you are making the assumption that wanting a baby of a certain race is supremacist, if that's true then any white girl that wants a mixed baby, or any Asian who wants their baby to look like them is a supremacist, is ridiculous. I'm black, you should listen how black people talk about having mixed babies (they don't want it). Life is not a history channel documentary, go out more.

Can such a thing exist as a white dating app that doesn't encourage supremacy and eugenicism, or is whiteness an exclusionary factor for the entire premise? How does this extend to other races having race cases dating? I'm coming at this as someone who isn't a fan of any supremacist ideologies.

I think the same. Why exist dating apps for all races but not for white?

Exactly
