Well, the same white men created Jim Crow and seggregation.
If you were a black man would you have been disenfranchised when those laws were in force?
I'd say yes.
The fact that it was/is worse elsewhere, e.g. in some places in Asia, doesn't make the critique (of how white Constitutional/law makers historically disenfranchised certain demographics in the US) invalid.
> you were a black man would you have been disenfranchised when those laws were in force?
In a counter-factual world where the founders hadn’t exported their ideas all over the world, I’d be disenfranchised in my own home country! Because everyone was disenfranchised. Everyone was a serf.
