Despite the massive co-optation of the MSM by capitalists and corporations, it hasn’t always been so. In the Post-WW2 Era, the U.S. had an extremely free press. Even after that - even now - there is plenty of information if you bother to look.
The meme that the U.S. population is faultless because of ubiquitous propaganda is about as grounded as the German populations saying they “didn’t know” during the Nazi Era. It’s impossible not to know unless you actively look away. Every human being has a human heart and human conscience, and only the most damaged should be excused from claims of ignorance.
