I will soon begin following you because you are the kind of thinker I want to endorse. It seems perfectly clear to be that the left seems to be fine of the Democrats are a permanent minority party as long as they are a party of minorities. And for the record women make up more than half the country to argue they are a minority is a little hard just on math?
The left has no strategy. Then or now. If it is, it exists purely in the world of academia or on some level of morality in which institutions are to blame no one wants to fix. The left seems to be proud when they push people away and they ahve the same "if you're not with us, you're against us." That would be nice if they told us what they were for, but since their de facto movement is to be against everything. And for the record I think the left's anger about the right compromising King is just their own blindness: by the end of King's life he was increasingly viewed as behind the times because he preached for unity rather than the separtism of the Black Power movement. People like hUEY Newton and Malcolm X increasingly thought King's strategy wasn't in their peoples best interest. The fact that it happened to be working in a way there's never did is something that they chose to ignore.
The left has already begun doing what they always do when the Republicans win - blame everybody but themselves. Of course since their loyalty to Biden basically ended the day he defeated Trump (certainly based on the articles I saw during his administraiton ON THIS SITE) no election in the history of America has ever gone its way. That they refuse to define what their way is for the rest of us is not their problem but proof that the rest of us are racist, misogynist, homophobes and the biggest sin of all, ignorant. Of course some people might say because they're so enlightened they'd tell us how we can bring their utopia about or at least what the vision is. But of course what do I know? I'm just unenlightened because I don't have the vision that these people have for utopia but have never deened to share with us. I'm sure they'll tell us soon. It can't be that they don't know what it is.
