No, I'm not trust me, I am aware of the relative ambivalence of current youth...
...where I think you're missing a dimension here is that within the younger generation in the US is a tremendous sense of entitlement and thus anger at what 'the patriarchy' is doing to them. Given that the choices last week were two very old white gentlemen, you can pretty much guarantee that young voters felt very disenfranchised and unmotivated. With Trump going off again on his border/immigration rants, and Biden doing the right thing, Harris (with the right veep nomination) offers a very clear and tangible alternative for the first time since Obama. So there is a great chance to mobilze a previously unengaged voting base to make sure the GOP and their flimflam doesn't get across the line.
Like yourself, I have a certain set of feelings towards how it all works. The cynic in me knows how little of what we currently have is down to the choice of individuals rather than the course of economics as charted by the select few who wish to mainsain their fiscal status quo. But I will say this; what is going on in the US is about as serious as it's got with regards to ripping up the way things uneasily work and replacing it with an autocratic, facist dictatorship where vital positions get held by 'friends' who will 'do the bidding' of their leader. I know some here think it's all a game -it is to an extent- but the game got very dangerous in the last 6-7 years. The Supreme Court thing is real. And whatever happens in November, the US will enter a period of either extreme dictatorship or small pocket civil war. We're there!
So we/I have to hope that there is vast tract of youth and women who've previously felt ignored that suddenly realize unless they help make the difference, their (and our) lives will be in the hands of theocratic Christian nutters, facists, and some very angry, scared people.
