I've been active online and in an actual communist party for years now. I am yet to be approached by a Chinese or Russian official to be a paid shill. You'd almost think it is projection.
Just remember, in the US, Nazis have more rights than you. For example, protections under federal labor law specifically do not apply to communists. Great country, eh?
Government jobs, yes. Lying could result in jail time, in some cases. Jobs here are also known to pay people to search social media for dirt. Really just a matter of time before they decide to start trying to use it again to avoid wrongful termination fines.
More than anything, I think it's important to highlight how fucked up it is that it's still on the books and no equivalent anti-Nazi laws ever have been.
