The Progressive Movement gave us the 16th, 17th, and 18th Amendments (1 repealed, 2 to go). It also showed a disdain for free speech, except when it was Progressives’ free speech. It planted the seeds for the Liberal crap we’ve suffered under for a century. Liberals/Progressives need to be fought, not debated. Debating with a Liberal/Progressive has as much value as would debating with someone from ISIS.
You can't debate a liberal, because they refuse (or are unable to) discuss the issue at hand. It always devolves into name-calling and subject-changing.
