Pure Democracy IS mob rule. That's why it's immoral. That's why we don't live in a pure democracy, we live in constitutional republic.
It is.
If 75% of Americans wake up one day and think the Constitution and the Bill of Rights are BS... and they then vote in politicians who encourage this, they throw out the Constitution and make up "rights" that contradict the Bill of Rights, you'd have to support that. So, if that included saying it's okay to kill someone who you don't like.. if 75% of Americans said "we think it should be legal to kill people we don't like".. your logic supports it. Mine does not.
That's why yours is immoral.
