There are a sizable number of anti-Zionist Jews, but their voices are always drowned out because their opinions don't matter. Big Jews always use little Jews for their own ends.

I think a good number of the hasids believe that the jews are not allowed to have a nation until their savior comes. They believe that the State of Israel is illegitimate because of this. I read some press out of israel and they are called "anti-semetic" on a regular basis.

Is it possible there are some decent human beings among rabbis?

Only if you consider sucking the dick of newborn babies ok.
