Fir puts it succinctly:
I’m always hearing people say how, “I disagree with your opinion but I respect your right to have a different opinion than I do.” That just makes me sick.
If you disagree with me, then you’re wrong.
No! I don’t respect your opinion, we can’t all just get along, and I don’t respect your right to be wrong. If you don’t agree with me, you’re Un-American, and a traitor. That’s the definition of Unpatriotic. It’s disagreeing with anything I say.
If you don’t agree, then I just need to ask why it is that you hate your country so much. Huh? Why do you hate America, traitor?
As my bubbe would have said, "Gut gesogt."
