There are almost 0 actual communists in any position of power anywhere in the United States. The fact that you think there are any communists in positions of power in the States is pretty funny though, I'll give you that.

There are absolutely many neo-Marxists in positions of power. They form the HR and PR departments of major corporations, they are the editors of newspapers, they are the directors of movies and TV shows. They are the leaders of Black Lives Matter, which has been praised by governments and corporations worldwide. They have internalized totally a religion of equality in which different identity groups are viewed as "oppressor" and "oppressed" (in contrast to traditional materialist Marxism in which class is the sole consideration). By constructing these ideas, they invoke an inverse force against those designated as "oppressors". Class is simply lower down their list.

I sympathize to some extent with traditional Marxists who feel that this craziness has really taken things off course, but this is yet another case of "this isn't real communism" when this is literally how communism has gone every time. Purges of dissidents, purges of those who initially helped to tear down the old system, tearing down of monuments, destruction of culture, and concentration of power in a tiny elite while average middle-class people have their quality of life decimated. All we're missing is the famine.

U.S. Communists would actually very much understand why banning speech is bad, if anyone would, since historically it was Communists who were blacklisted in the 50's in our country. Even if they had only attended a meeting or two at a time when that was quite common.

They understand why banning speech is bad for those who are banned. It's become quite clear over recent years that censorship works and all of those centrist copes that "censorship will drive it underground and make it worse" just simply weren't true. They're quite happy to censor others to protect their power as we can see today.
