Of course I am! It's a derogatory term. No attempt to make it a "friendly ribbing" term will change the true attitude of those who use it.
It was coined, and only used, by liberal-leaning or worldly Traditional Catholics.
Who do you ever see the term aimed at? Those who reject the world, those who totally reject the Conciliar Church and the Novus Ordo, those who would never attend a Novus Ordo Mass, those who don't own a TV, those who are sticklers for Catholic morality, etc.
Just like the word "nigger" became a term of contempt for black people in the late 20th century, despite the fact that some blacks use the term as slang or even a term of endearment among themselves.
Replace "rad trad" with "nigger", and "traditional Catholic" with "black person" and you have the situation pretty well summed up.
