There's a very good reason why the word "maizlish" is considered a derogatory term in many Star Trek stories...
Huh? I know David Gerrold has made a point of trashing Maizlish in everything he's written for the past twenty-odd years, but I haven't seen that manifest in any Trek fiction I've read. Are you referring to fanfic?
Yeah, I didn't know this either. I've certainly never seen it anywhere that I can remember.
