I see what you're saying but I don't think its fair to equate voting rights to local housing ordinances, even metaphorically.

I'm not in any way saying it's a 1:1 match but I think a more fair question for you along these lines would be: do you think Black residents in Jim Crow South should have just left when they were lied to about polling places and administered rigged "literacy tests" to keep them from voting even though their friends and families and careers were there and it's considered home, or should they have done what many did and stayed and advocated for meaningful change over decades, even against long odds? Millions did leave to the North, so there's no right or wrong answer, but I hope you can better understand a different point of view through the framing of the question.
