You'd have more success in trying to use this argument for why passport bros exist.
Because if you can't get (who you think are good looking) white women then you'd go down the ladder of attractiveness and get some whale cacette that'll take you.
Since most brehs can at least get that.
What you wouldn't do is become
more militant to further limit your choices.
Because I think it's legitimately surprising to some Black people (Men and women) that some in their group legitimately don't want whites as partners. At all. And yeah it's because of centuries of history and all that they've done. Which everybody on earth knows about but strangely pretends is an ignorable issue.
But also because it doesn't make sense from an economic perspective.
Since you can't build anything that lasts with your obstructer and your wealth won't stay in your community.
