Is it wrong that I only want to adopt white children?

I could understand it if it were because of concerns about other kids / parents questioning the adopted child's parentage on the basis of appearance and treating them differently for it.

But because you want to 'help out your race before others?' Adopting a child shouldn't be some act of racial charity. A non-white foster kid is as much in need of a stable and loving family unit as a white one. If you picked an asian kid, it wouldn't somehow benefit all asian people, just as you picking a white kid doesn't somehow benefit all white people. So dumb.
