Karl Marx was a non-practicing Jew who denied his own Jewish heritage, and we see in our time a wide range of Jewish Americans who are rabidly pro Left.
I don't mean this in any way as a slur against Jewish people, but only a statement of fact. To me it's a strange phenomenon that so many Jewish people seem to prefer Marxist statism rather than a more decentralized solution to government such as is establish in our Constitution. Yet National Socialism (i.e., Nazi) and Soviet communism destroyed the lives of more Jewish people than any other form of government ever devised. Perplexing.
As a conservative Christian, who fully supports Israel, I share your same bewilderment over liberal Jews in this country USA, who voted over 75% for buruck husssain odumboshiite in both 2008 & 2012. Incredible!
Hardcore left-wing marxist ideology will ALWAYS trump (no pun intended) family ties, ethnic or religious background. The most evil people in America right now, seem to be Jewish people - Soros, Schummer, Al Franken, Debra Wasserman-Schultz, Henry Waxman, David Axelrod, Rahm Emanuel, etc, and the list goes on....Incredible!
Soros is a second generation atheist, a declared Magyar, and a former member of the Arrow Cross; not a Jew.
