To be clear, black people having the right to vote wasn’t the original deal, either. Was them achieving the right to vote disenfranchising white people?

That’s the problem here. Yes, black people achieving a say in how they were governed lessened white people’s power. Clearly it was the right thing to do. Unless you’d like to argue against this point?

My argument is that favoring rural over urban is not dissimilar. As a matter of practice, favoring rural _is_ the same as favoring white, Christian (especially evangelical) land owners.

Your fears over “one person one vote” nullifying smaller states is just not reality. Most countries don’t have a Senate-like body and their smaller territories are not wastelands. Thinking it would nullify their voters is not based on real world observation.

As a matter of fact, smaller states derive more benefit from cleaving to bigger ones than the other way around in nearly every way. The world provides plenty of evidence that disproves your arguments, we don’t have to fear theoreticals.
