You're misunderstanding the purpose of the Senate, whether Wyoming is 80% white or black or any other random race. The point is that it exists as a sovereignty vote. To take it away would be to cause a civil war or at least a dissolution of the United States because smaller states will walk away.

A lot of the anti-American, anti-Senate, &c. stuff is Russian propaganda precisely because to continue to sow division and encourage populism is to invite destruction and disunity upon the United States.
