The Left-NIMBY canon
We’re all familiar by now with Right-NIMBYs conservatives who block transit and housing development in order to keep poor people and minorities out of their quiet white-flight suburban neighborhoods. These are still the most common kind, given that Republicans tend to value low-density communities while Democrats tend to value denser, more walkable places. But liberals can be NIMBYs as well, as any resident of a deep-blue state or city well knows.
But leftists can be NIMBYs as well (and remember, leftists and liberals are generally different people). In various cities, concerns over gentrification, environmental preservation, and profits for private developers have hardened into a sort of Left-NIMBY Canon a standardized, off-the-shelf package of beliefs, attitudes, and arguments that are easy to deploy in opposition to nearly any proposed housing or transit project.
