Not to offend anyone, but a theory that I had holds true most of the time: you cannot trust people that come from Communist countries; even if they escape, or have come over since the Iron Curtain fell, they have been brainwashed.
I’ve worked with too many people from communist/ex-communist countries to overlook what I’ve seen from such ‘comrades’.
But there have been some exceptions! I’ve read about a number of them on the web. Some of these sort have turned out to Tea Parties!
