The Guardian newspaper (here and here), Amnesty International (here and here) and Ynet have been among the outlets reporting on racist and eliminationist graffiti left behind by Israeli soldiers in Palestinian homes they took over during their recent attack on the Gaza Strip.
I noticed that "ahmed", a commentor at mondoweiss, remarked as follows on that blog's discussion of the Ynet report: I guess it's only a hate crime when the drawings are swastikas. Perhaps "ahmed" was being somewhat ironic he wrote that comment; but he also happens to be correct.
That kind of graffiti pops up often in the streets of Jerusalem. Leftists have found that the slurs remain on the walls a long time so to hasten the city's action against them, they've found a chilling, but effective way to get them removed - they paint a swastika beside it.
So, next time you're strolling through Jerusalem with your can of spray paint, and wandering what best to write to ensure your graffiti immortality, just remember:
"Arabs to the crematoria" + shield of David = not offensive + allowed to remain;
"Arabs to the crematoria" + swastika = offensive + will be deleted.
