Most of the time I find people are just repeating talking points from one of the two popular narratives in culture. Capitalism good, or capitalism bad. Its woefully incoherent as both sides seem to be most of the time.
And for some of the (seemingly) low IQ stackers, the left is far more off on most things than the right. But the left does make some valid criticisms of the right. As many say, tribalism overpowers logic and reason.
