Sadly, you're right. More to the point there are many examples of the US knocking down anything or anyone even suspected of threatening capitalists. Whether that's unions within the US, governments leaning too socialist (yet being democracies), or whatever else. I know you know this; I just felt like venting.

When they all come out with new talking points about the same time, all bearing remarkable similarity, and coinciding with notable (geo)political events, and brigading certain posts, it sure makes you go, "hmm."
