Democrats use the term, "Democrat" often themselves. This is nothing new.
What is new is the faux outrage at the use of the term. No normal person is upset or even aware that others are upset with the word, Democrat. I work in a liberal heavy work place: they all use the word democrat to refer to themselves.
Certainly, calling me a "publican" is not an insult.
This is all pretend, sissy stuff. Real men don't play with semantics.
