I think progressives never thought about this because we banked on immigration and demographic change allowing us to win culturally and electorally but the issue is immigrants tend to be overwhelmingly male, that is how Trump won actually he won over a lot of Hispanic,Black,Asian and indigenous men who feel humiliated by a new culture, economy and world.
So what can we do rhetorically and policy wise to win more young men over ?
I think instead of focusing on how to sell this product, we focus on the product itself because it’s impossible to sell something that Democrats keep pulling off the shelf as “defective.” Like any other item that people buy, committing to something only to have the “company” do a 180 and stop supporting it immediately after your “purchase” is just going to drive people away.
Most Democrats only seem interested in pushing progressive policies right up until they get elected and then it’s always “not the right time” after the election.
Edit: also the product would sell itself if they actually implemented them and improved people’s lives. It’s kind of hard to deny things that exist right in front of your face, but we never seem able to get to that point because corporations and genocidal “allies” always take precedence over the American people regardless of which of these two parties hold office.
