The left has abandoned the working class. Jordan Peterson is right, marxists don't love the poor - they hate the rich. That is very different.
Trump excited the working class, especially the working class whites, because although he was born with a silver spoon and has been listed on forbes, he says the things they think but "can't say".
The left cuts down every individual into a group of categories. There are two larger categories that govern these smaller categories: "Oppressor and oppressed". The smaller categories are: gender, race, sexual orientation, nationality, gender identification, class, and religion. But fundamentally, people are not reduced to their membership in these categories. A black man does not equal another black man. A woman does not equal another woman. And so on. There are differences within classes that are greater in magnitude than the differences between classes. This should be proof enough that identity politics, while rhetorically useful, are false prima facie.
On Roseanne. She's nuts, whether you like her or not. She has multiple personalities, she is impulsive as hell, she's off her rocker. Forget all that. Why was her show cancelled? Not because of what she tweeted. Her show was cancelled because its ratings tanked after a few episodes and nobody is watching. This was a convenient excuse.
