Relative to the kinds of places many of it's residents come from it is a paradise of individual liberty.
Relative to the rest of Maine it is the most authoritarian by a mile.
People from Portland (cue joke about them all being from MA) wouldn't blink twice about a local ordinance that would have the people of Bangor or Lewiston up in arms. I'm sure they don't mean to be authoritarian and it's just a reflection of the cultural norms from the places many of them come from and everyone else keeping their mouth shut (because nobody wants to rock that boat in a tourism economy) but having a reason doesn't excuse it. Yes I know I'm generalizing, please don't paint a straw-man and act like I called your hardliner libertarian uncle from Portland an authoritarian. Clearly I mean it at the statistical level and mean it relative to the other parts of Maine.
