You're being glib and forgetting important concepts like the tyranny of the majority, etc.

Overrepresentation of select groups doesn't prevent tyranny of the majority, it makes it more likely (and tilts which majority is likely to enjoy it), and even makes tyranny of the minority possible.

Tyranny of the majority can only be prevented by establishing norms that limit what government can do even with support of majorities in representative institutions either as absolute norms or with some things requiring a higher bar than a one-time majority (bicameralism with both houses not being elected fully simultaneously does this, requiring concurrence between branches does this, supermajority requirements for certain actions does this, Constitutional limitations with amendments requiring supermajorities of states even after legislative passage do this.)

Because tyranny of the minority is much better...

> Because tyranny of the minority is much better...

That comment is basically a repetition of your last one with no further explanation or elaboration. It's pretty clear that you have the opinion that political representation should only be proportional to population and that all other systems are bad. We can't have a discussion if you don't want to engage other ideas.
