I worked with a public union and some of them are communist and proud of it. They got a guy, Mark, elected to State office. One of the union leaders, a communist (Jewish)had lost his father and one of the meetings that I had to attend devoted some time to his memorial. Mark got up and boasted about how he was a former Republican businessman and after he came to know the deceased he was now even more of a communist than the deceased.
A contract lawyer at my last company had communist parents and he called himself a “Social Democrat” — aka, communist.
The woman who did our kitchen remodel design work was a communist.
I challenged both of them after some discussions and they both admitted it.
The weird thing is they are both self-employed and making boatloads of money.
