This is category error, at a minimum. 'highly progressive people' is an abstraction and cannot take action. It's imagine it's also inductive reasoning and out group bias.

This was my experience working at Google. Very liberal until you start talking about upzoning, then suddenly "some neighborhoods should keep their character".

Very liberal until it's time to actually solve their own backyard's problems eh.

NIMBY does not mean conservative. Indeed, one of the most annoying things about NIMBYs is that they come in all political shapes and sizes. :)

They also complain about ghettoization as soon as certain people come to their neighborhood.
