I tend to be more sympathetic to the progressive-left's economic message than their racial message, which is non-liberal, promotes race hate, victim hierarchies, violence, and national divisions.
I think, however, that it goes off the rails when it assigns malicious intent to those who disagree.
You quote Bernie Sanders:
"Trickle down economics is a fraudulent theory designed by the rich and their think tanks in order to protect the billionaires and large corporations."
Or it is a flawed theory designed to lift all economic boats.
See, that's the difference.
You want to instigate "class war" whereas I just want to see a continued steady decrease in poverty levels.
We both agree that "trickle down" economics makes little sense. My opposition, however, is not grounded in Marxist ideology but in general common sense. Merely because a corporation receives tax breaks for the purpose of increasing profits does not mean that this will translate into the hiring of more labor.
Where Bernie and I disagree is that he seems to view trickle down as a cynical attempt by bad people to rob regular Americans on behalf of the wealthy.
Sadly, I have no such mind-reading abilities and am also perfectly aware that people can promote the worst ideas while doing so for the very best reasons.
For example, much of the progressive-left promotes the notion that white people, particularly white men, are a nefarious group in need of a good ass kicking.
This view is promoted by "identity politics" which posits a hierarchy of racial and gendered victimhood and dockets people (by skin color or gendered orientation) on that hierarchy.
In this way it recreates the very thing that MLK, Jr. warned against and does so, laughably enough, in the name of social justice and universal human rights.
