In another thread, a commentor used the term nocoiner, which was the first time I had seen the word. It's pretty obviously part of "in group" jargon, used pejoratively to describe people that disagree about the efficacy of Bitcoin. Anytime I see made up terms used in a derogatory manner, I assume the user has gone too far down the ideological rabbit hole, and I can dismiss whatever it is they have to say without much consideration.

I think it does parallel a religion to some extent, in that it's like being called a heretic by a religion of which you are not a member. It's just hard to take seriously.
