Oy,vey! They’re Jewish!!
I have no doubt that there are MANY Jews who find their behavior and actions utterly repulsive and not at all in keeping with the teachings of Judaism just as I have such feelings for some who profess to be Christian yet conduct themselves in decidedly un-Christian ways. It's unfortunate that they've chosen to wrap themselves in the visual trappings of Judaism and present such imagery as a primary part of their public image, perhaps in an effort to gain sympathy and support from Jews or from those who are simply impressed by such displays.
