Only the Haredi Jews preach extremism. They have been denounced by the rest of Judaism. A little tidbit.
Wrong. Many Orthodox Jews believe in and preach extremism and bigotry towards non-Jews.
Ive heard Orthodox Jews call other Jews "Goys" simply because they use profanity.
Ive hearrd Orthodox Jews say that when the Messiah comes, all Gentiles will be slaves to the Jews.
Ive heard Orthodox Jews say that the Germans are the descendents of the Amalakites and are too be forever punished.
Ive heard Orthodox Jews say that blacks are the descendents of Ham and Cain, and are forever punished by God and have the mark of Cain.
It goes on and on.
Are you serious?
"I've heard" does not qualify as a substantive explanation. Prove it. Your bigoted interpretation of the Jewish people is proof enough you have no idea what you're talking about. Only seriously malinformed individuals such as yourself give in to social stereotypes of other people.
But, but, but... there are "extremists on all sides", right?
