Seriously, life is too short to be an adherent. I suppose it must be comforting in some way to stop thinking and obey. But it sure doesn't make you smart.

adherent =/= zealot.

In all contexts, no. In this context, yes.

Yeah, most people probably knew what you meant and would agree. Blessed is the mind too small for doubt.

I for one am probably too dumb to know what you mean. Are you referring to the adherents of veganism or the adherents of meat eating? Both? Which group isn't thinking and obeying? I'm confused.
