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?

lol i laugh at you all for the sole fact you take whats put on you plate and believe that its the only thing that exists...you dont even know the truth of the land that you all argue that the Palestinians should have control of. Read mother fuckers israel was the ancient land of the jews befour the muslims even existed...then they came in and forcefully took it from us...now we take it back again and you all cry and moan about it..you have proven nothing then the point that you are all blind to the very truth that exists in that land...i pity your ignorance.
