Forget the israeli government, but is it wise to put groups like this in face book?
I think so, actually.
I think "pushing the boundaries" of discourse at this time is really important in fact because a basic, sane rightwing view has been marginalized to such an extent and basically labeled racist and beyond-the-pale, so there really is no rightwing voice within the realm of discussion anymore. With groups like this, it will give courage to rightwingers, bring them out of the closet, and embrace their more sane views and start saying them aloud.
I mean something like this, a person's thought process would go like this: If someone else can post “How nice to see the people of Israel waking up and fighting for our right to exist! Death to the Arabs, Muhammad is a pig!” and truly believes that and is willing to openly say so, surely I can say I oppose the Oslo death process if I disagree with it.
Btw, I actually agree with that quote completely, but even for people who are more "moderate" rightwingers, who maybe wouldn't say something as extreme as that, I think they are emboldened by rhetoric like this. At this point in the game, personally, nothing so minimal like harsh rhetoric is out of bounds for me when it comes to opposing surrender to the arabs.
