how can we convince people Israel sucks?

I've taken part in a whole bunch of Zionism threads, and I've noticed that despite my mountains of evidence that modern Israel is a bloodthirsty, militant leech that offers nothing but pain, misery and debt to both America and her neighbors, people seem intent on defending her.  I've also noticed that very few minds are changed in these debates; i.e. people who support Israel continue to do so and people who don't support Israel continue not to.

What new tactics can be used to convince people that Israel, in it's modern Zionist form, is a scourge upon the land?

zionist jews have murdered thousands upon thousands of palestinians since the 1920's, when the jews started taking the land by force.  it's no wonder the muslims want to wipe it off the face of the earth, isreal was a huge fucking mistake with no right to exist.
