Those people aren’t progressives: they’re NIMBYs who learned that certain language can make it easier to get the policies they want. We have a ton of them here in DC, and you can tell by seeing what else they support: they’ll talk about affordability to block luxury apartments, flip to pretending to be staunch environmentalists to block an affordable housing project, talk about traffic or “the poor” when protesting a bike lane before pivoting to block transit projects, etc. It seems incoherent until you look at it through the lens of whether something would add competition to their future home sale or cause the city to subsidize them driving every everywhere less.
