Why did this maniac target Jewish people?

EDIT: March 21, 12:02 AM--There are news reports suggesting that the lead suspect is of Algerian heritage and is a member of al-Qaeda. As I type this, the French police have him cornered in a multi-family house near the Jewish school in Toulouse and they are trying to negotiate his surrender.

CBSnews.com is reporting that a gunman on a motorcycle took aim at Jews in Toulouse, France, killing a rabbi, two of his children and the 10-year-old daughter of the director of the Jewish school where the murders took place.

CBS/AP) TOULOUSE, France - The shooting deaths of four people, including three children, by a gunman outside a Jewish school in the French city of Toulouse has been linked to two deadly attacks in the same region last week that killed three French paratroopers and left another seriously injured. Investigators said Monday that forensic tests have shown the same weapon was used in all three attacks. The motive is unclear, but the targets all have been ethnic minorities.

A 30-year-old rabbi and his 3-year-old and 6-year-old sons were killed in Monday's attack, just before classes started at the Ozar Hatorah school, a junior high and high school in a quiet residential neighborhood, Toulouse Prosecutor Michel Valet said. Witnesses said the man worked at the school. Police identified the fourth victim as the 10-year-old daughter of the school director. A 17-year-old was critically injured.

Based on what has been reported, my guess is that the killer is not part of al-Qaeda or another Muslim terrorist group and probably is not a Muslim, despite the extreme anti-Semitism of the Muslims of France.

My guess is that when this murderer is caught, we will discover that he is more of a psychotic than he is political. He probably suffers from paranoid delusions.

Yet I cannot help but think that, if that is correct, he has been influenced by the everyday hatred of Israel voiced in French political discourse and to lesser or greater extent elsewhere among the European left. We see this hatred of Israel in the American left, as well. However, it is more than counter-balanced by the American right and center. On the whole, Americans tend to like the one, free, democratic state in the Middle East, whose culture is similar to our own. By contrast, Europe in the main has for the last 45 years--since the Six Day War--sided with the fascist police states which surround Israel. The large European left has excused the horrible, violent behavior of the Palestinians. They have equated Jews defending themselves from terrorists with Apartheid in South Africa. In the face of widespread anti-Semitism, the left has branded Jews as racists and oppressors.

That context, those lies, this culture has created a climate in France which, I suspect, made this lone psychotic think murdering Jewish children and a rabbi was the right thing to do.
