There's nothing wrong with this sentiment, but I think there is some common sense points I have to make whenever this topic comes up.
(a) There's nothing wrong with dating people of color, and personally I think it's commendable (and good for your community) when Black men seek out Black women for their life partners. I have nothing but love for that.
(B) At the same time, Asians, Hispanics and Middle Eastern folks can be just as racist and ignorant as White people and even possess relatively more privilege compared with us. So I don't really think you're, necessarily, better off dating an Asian person over a White person. I say this as someone who hangs out with Asians a lot because of school and is even dating a Chinese woman. My girl is cool but plenty of them are worse than the White kids here.
(c) Every relationship is different. My mom remarried to a White guy after leaving my Dad (Black) a while back, and even though my Dad is real cool, I think she's happier now. My stepdad also understands every point you listed there, so I never feel the need to smack some sense into him. At the same time, you definitely do have some dumb ass Uncle Tom's who just won't even date Black women because of how fucked they are in the head. Really, I think you just have to judge every relationship individually instead of putting people's love life into simplistic boxes.
That's pretty much everything I feel about this topic, feel free to disagree.
