You can spend all day criticizing people and organizations in power in the US. The most powerful people, the most powerful companies, and everything else. How is it true except as a dog whistle for conspiracies? You can literally spend all day calling whichever president happens to be in power a cunt, along with every congressperson, judge, General, and CEO. The people who literally have the power of life and death over the citizenry are constantly criticized.
Maybe the origin of the quote is important to understand what it really means. It’s a dog whistle to claim that insertgroup is really the power behind the throne. It was a way of saying that because it’s considered bad form to be a Jew-hating Nazi, and most of society will despise you for that, it means that Jews really run things. Changing Jews to some other group doesn’t change much. Claiming that gays or blacks or “lefties” or whichever group you think are really in charge because you’re not supposed to denigrate them, isn’t a good point, and using a Nazi pedophile’s quote to make it is telling.
