In other words, it's not a very useful way to look at the issue in my opinion.
Trying to map the high-dimensional "vector space" of political views onto a 1D line is very, very lossy, and definitely not useful outside of the very narrow context of general elections in a two-party system.
The caricature doesn't really help things.
Even most “YIMBY” supporters are actually “Yes In Your Backyard”, because nearly everyone has some local environment they want to protect. Don’t want a pork rendering plant or a sewage treatment center or a strip club next door to your home? Congratulations: you’re a “NIMBY” too! It’s a sophomoric epithet that makes you feel good and superior to fling around, but does nothing to convince people who don’t already agree with you.
If you don’t understand this, you are doomed to fail to achieve your goals.
in other words, virtue-signalling about vague, general principles of increased development...buuut when that development actually impacts them, well! That particular project is just flawed for various reasons. The general idea is good! But it won't work here.
It's the equivalent of the boss who totally supports unions but, you know, a union just wouldn't be right for our particular company culture.
So, yeah, "yes in your backyard" is just the original definition of a NIMBY.
