I suppose that this is in response to a recent attack against a man wearing a Jewish skullcap in Berlin [1]. The crazy bit is that the man attacked was a Syrian Muslim who was walking around with the skullcap to see if Europe is safe for Jews. The guy who filmed the attack was an Israeli Arab!
I'll admit, though, this article interests me because I'm an Israeli Jew. I'm really not sure why it is on Hacker News.
