There appears to be no widely accepted antonym for “civil libertarian.” So how about a contest? Please post your suggestions for a new coinage in the comments, and I will select a winner at the end of the day. The winner will receive a free Pileus t-shirt the approbation of the impartial spectator and one’s peers.
authoritarian, or if you’d rather go the Orwellian route Inner Party
Pnyxaphobic.
“Communitarian” seems closest to the antonym of “civil libertarian” if one is looking for a term embraced by others that is not designed as a slur.
Civil regressionist….
Civil Dependant
So far I’m leaning toward Random Guy’s entry, because I’m looking for a term that sounds at least neutral & is less of a mouthful than “relatively deferential to the police power of the state.” “Communitarian” might fit, since noted spammer Amitai Etzioni, one of the few self-declared communitarians, certainly takes a dim view of privacy & speech rights.
As far as highfalutin slurs go, I do like “pnyxaphobic.” Had to look “pnyx” to get it.
Governmentarian
“public patriot”
