Earlier quoted context omitted.
This statement is a touch misleading. Portland's the only thing resembling a city in Maine, so it's going to have a larger government, organized police, etc, compared to the rest of the state. However, I wouldn't describe anywhere in Maine as being remotely authoritarian in the first place. The disclaimer being I haven't really spent any time up north, but I suspect no one is alleging authoritarianism north of Bangor…
I grew up in Maine, and I think the statement is quite accurate. Portland is not authoritarian, but it is by comparison to the northern counties
Just because Portland has zoning laws and historic districts doesn't make it authoritarian. I'd argue Portland is pretty minimally restricted compared to any other US city. Besides not being able to shoot guns in the middle of the old port, and having some red tape preventing you from knocking down the west end to build steel and glass buildings, I'm curious what is remotely authoritarian about the place.
Then again, I'm from a bit south of Portland (and originally from away, which Mainers seem to care about in perpetuity), and moved away to SF a couple years back. My perspective could just be off?
