I truly applaud this thinking as I've made arguments of it in my own articles, albeit in somewhat harsher terms.
The liberal elite do have a class structure and it is based in both the urban areas and the educated. I'm read so many articles in liberal magazines and progressive outlets secretly cheering whenever its announced red states are suffering more than their precious blue states, that Republicans are losing among college educated voters, minorities and all 'real AmericanS. That the Democratic Party has been losing the working class vote steadily - in the 2020 election Joe Biden got less than forty percent of it - is the natural progression of a party that increasingly embraces the elite and educated and tends to dismiss those who are working class and don't have the money to finish college as - well, it has to be said - deplorable. It's the main reason progressives have no desire to even camapaign or build a democratic party in the south or the rural west. There are, last I checked, African-Americans, LGBTQ+, women and even Democrats in all of these states - Trump didn't get 100 percent of the vote in all of them - but for so many progressives and leftists, they might as well not exist. Honestly to them if you're one of the precious few who lives in Mississippi or Idaho or Wyoming? The best thing for you to do is to move to a purple or blue state. And if you can't afford to do that, tough crap.
I've railed against the exclusivty and prejudice of the left more than the right on my blog for a simple reason. For all they're talk on believing in equality, and protecting the rights of the downtrodden, they have no solutions, pragmatic or even unrealistic ones to get them. They haven't had them in two hundred years: they have never been as popular as their ideas have been. And that's because - they have no more use for how democracy works then the far right does. They are not pragmatic and they don't believe in compromise. The only reason they're part of the Democratic coaliiuon right now is because they're not large enough to be viable on their own as a political force in America. Given so much of the attitude of 'The Squad' and their supporters they have lots of slogans but no way to implement them. That's been the textboolk model for progressivism for over a century and a half: they view the world as binary, with their position as the only correct one. Such details as pragmatism or popularity are irrelevant.
