That's why I start most political "discussions" with intractable Liberal Progressives with the simple phrase: "Go f**k yourself!"
That tends to save me a lot of time and headache since they are ignorant of history, the constitution, economics, and Americanism. They are not worth speaking to, let alone reasoning with. So, I just cut right to the chase.
The half-educated ones are the worst. They think they know what they're talking about, but refuse to even consider that there are a million other viewpoints out there, each as legitimate (at face value) as they think their own is. It's like talking to a wall, a loud wall that shouts back spoon-fed rhetoric.
