Jeez, don't any of you people work for a living?
IQ tests are bogus. I consistently measure in the low 150's, and that's proof enough for me. Besides, I grew up in a family of certified geniuses, and, love'em as I do, sometimes they the dumbest people I know.
I don't know when the whole "the Jews are the smartest people" thing got started, but I do remember reading a book on the topic back in the late 1960's or early "70's that was all the rage for a while. It was written by a Christian scholar who's theory was that Jews essentially bred for brains, pushing their best and brightest to become Scholars, Doctors (principle of Kiddush Ha' Shem), and Rabbis, marry and sprinkle the earth with their offspring, while Christians pushed their best and brightest into the Church, where all they had was altar boys, thus effectively removing them from the gene pool. If that makes sense to you, the author may have had a point.
As for all of the PC whining, I'll pass. It's been done to death here and there are about as many threads on it as there are threads on "How Do I Clean My Pipe?"
OK, I won't completely pass, 'cause I'm in a mood. Freedom requires responsibility to be maintained. Many want freedom without responsibility. It's like they want the right to go to their neighbor's house, climb up on their dining room table, drop their pants, and squirt a dump on their neighbors dinner, and act like it's just fine because it's freedom. Nutz.
