I live in Oakland, in an expensive neighborhood near BART full of single family homes, and very much support rezoning my neighborhood to allow for 4-6 story buildings, and would take those buildings on my own block. No, I am not willing to tear down my own house and inconvenience myself for years while building a 4 story multi unit building. But I would wholeheartedly support a neighbor doing so. I want more people in this area, I want the commercial activity that higher density brings, I want the added demand for public transit investment, more restaurants, more diversity, etc. That is in stark contrast to the typical NIMBY view. So you can call it something else if you want, but there are definitely differences between mentalities.
