If you're at a party and you find individuals on a totally different wavelength from you despite many discussions and nothing further can be gained, it's best to ignore them. Either they'll leave or just talk among themselves.
The same should apply here.

I agree totally. The extremists in here have enough screen names between them, to float a battle ship and bulldoze a village, all at the same time. Let them argue their self aggrandising and destructive ideas among themselves. The folks who do that at parties are considered boors. Israel doesn't need their narrow minded blather that will only bring her destruction and/or disgrace.
