A reader alerted me to this video, which features the lyrics "I wanna blow you up yeah Jew boy come on":
The person who uploaded it claims to be Hassan Firuzabadi, Chief of Staff of Iran's Armed Forces. This is highly unlikely, especially when you look at another more explicitly anti-semitic video he has posted, which includes shout-outs to Saddam Hussein, mentions "72 bitches" and whose chorus is "I'm a terrorist and I kill Jews":
I admit that these both appeal to my own twisted sense of humor, but even assuming that they are spoofs, I don't think that many of the people watching them are taking them that way!
Again, assuming that they are meant to be jokes, they might cause more damage than they intended. A cardinal rule to remember is that Jew-haters are quite stupid to begin with.
