But yes, there is indeed much bigotry coming from the left....misandry, ageism & racism.
What makes you think they're from the left? They seem like capitalists to me. The whole idea about vilifying "old white males" is rooted in identity politics, which is designed to make the rich richer, the poor poorer, and to divide the lower classes against each other. Ironically, it also gets all the wealthy and powerful "white males" somewhat off the hook, since it spreads the blame equally even among the poorest of "white males."
All of those quoted in the OP are people who occupy positions of wealth and power, so therefore they are just as bad as the wealthy old white men they're vilifying. None of those listed above are even trying to destroy the capitalist system, so they're obviously not from the left.
