You're a "wonky liberal", but it's the lack of sound evidence for progressive ideas that bothers you? Issues like climate change? Mass incarceration? Racism? Universal health care? Vaccinating people and wearing masks (not a position limited to progressives)? There's not another part of the political spectrum that lacks sound evidence?

That's a bit mind-boggling, but not the first time I've seen it. My hypothesis: Middle-ground liberals are intimidated by abusive conservatives, but they feel safe criticizing progressives. You won't get flamed on HN, for example, for what you posted.
