Part of it is that the left isn’t seen as fun. We’re too serious and judgmental all the time. Many times there’s good reasons for that but young people don’t want to constantly hear about taxation and proper pronoun usage. Talk about legalizing LSD or something once in a while.
And yes, I understand that the right isn’t fun in a way that most people would want to be but there is definitely something to be said for not gatekeeping language to an absurd degree. Let people express themselves without all the “well actually that’s ableist because…” interjections. People only listen to you a finite amount. If you burn through your educational goodwill on minor stuff no one is going to listen when you warn them about important stuff like fascists taking over the government.
I always picture some flat earth guy stumped about what is at the edge of the world and then he stumbles on the first episode of Game of Thrones.
