People say the same things here, where I know them not to be true, but I don’t know anything about your municipality. I know what the social science says about this, and the common sense intuition that never occurs to people to turn out in favor of apartments they’re not going to live in, but does occur to people who want to stop it. Your mileage obviously varies.

I'm betting the developers are for single-family homes not apartments. The only NIMBY I'm for is anti-SFH.
