Yes myself and a friend (who gave me the article) presented Arron Zellman's Interview from 1995-ish time frame in a Gun Magazine to Liberal friends, mine was a co-worker, his, his girlfriend. My co-worker turned white as a ghost when presented the evidence and mumbled away, ya but I don't care I still want the ban, his girlfriend was pissed and sort of had an answer similar to my friend..
You see you challenge their epistemology and it is to scary, that you are challenging how they know what they know. It makes all the liberal lies of what they know fall like a house of cards, and it is too painful, because you are going to their core.
They can't have it, they'd rather go on believing in the tooth fairy...
I have a relative whose favorite tactic is to dismiss anything that didn’t emanate from the union front office. Sad.
