"Your last statement sounds like a very dangerous generalisation to me, Ken."

Why do you think its a generalisation?

Israel has seven and a half million Jews, the United States over six. Together this represents about 85% of all Jews.

In the US surveys show 86% to 90% support the existence of Israel as a Jewish state and there's no doubt that the a larger majority in Israel do likewise with only somewhere between 1% to 5% of Israeli Jews not doing so.

If the Israeli state is considered a "secular, fascist, racist, colonialist, genocidal death cult" my statement is mere statistical fact:
The only debate might be as to the degree of that support.

As to whether that fact is "dangerous" yes: its been more than dangerous to the Palestinian people for a very long time: in fact it's been deadly.
