I think those folks are seriously misguided and tone deaf, but the idealism is laudable. We live in society where we can actually feed everyone and provide them healthcare. We done a great job at equality and heterogeneity. The liberal push to be inclusive of those on the margins of even that admirably open society is impressive.
The problem is the methodology. They are trying to push people too far too quick, and calling them names when they won't comply. That's a recipe for regression.
I'm sorry. Did I venture astray from the topic? My bad.
