Are Canadian Jews Too Busy to Defend Themselves?

My title is deliberately provocative. However, it is an unequivocal fact that in Canada most of those speaking out publicly in favour of Israel and against Hamas are so-called "right-wingers". And the vast majority of those people are not Jewish.

A prominent Canadian Christian blogger named Kathy Shaidle has written about this strange phenomenon here and here. And Ezra Levant, a Canadian Jewish blogger, has posted this. Shaidle is interviewed on Rob Breakenridge's show here (at 09:15).

Both bloggers ask a very important question: Why aren't there more Jewish people protesting against Hamas and defending Israel?

Putting my pollster hat on, I've thought of 5 possible answers:

1. They couldn't be bothered.
2. They were afraid.
3. They think that protesting is pointless.
4. They are actually against Israel's actions.
5. Other?

Your thoughts?
