You hit on the absolute truth of how liberals see themselves. I said this yesterday on FR but you said it better,
Believing in liberalism makes them better people, in their minds. Always wanting to “give back” I hear them say. Republicans are evil, according to them.
The term “liberal” is about as much an oxymoron today as the term “gay” is. It is an inverted hijacking of the original concept. It would be difficult (though not impossible — when it pollutes the “conservative” sphere it is particularly ugly) to find those as grim as some “gays” or people so parsimonious as some “liberals.”
A colleague of mine slipped and said of another colleague - “She’s a GOOD LIBERAL.” It was like she was saying “She is a good person!” so that if you are not liberal, you are not good or decent.
Today, I was applying to rent property and the owner paused to say that he hated the insanity of Trump supporters and he wanted me to know that. Really - he can’t get a rent check from someone who votes differently?
