Abolishing the right to filibuster as the author proposes would truly make our democracy "two wolves and a sheep voting on what's for dinner".

Sorry Mr. Nutting, but there's no "tyranny of the minority"...

Tyranny: "A government in which a single ruler (a tyrant) has absolute power"

The minority can't enforce their wishes on anyone directly - they simply have the power, if they are a highly significant minority, to stop certain wishes of the majority being forced upon them ("tyranny" of the majority). Minorities having some power to block actions of the majority is a great check on government power, and we're fortunate to have it.
