What is this whole "the Jews killed Jesus" nonsense anyway? It was the Romans who crucified him.
Besides, I thought the whole point of Jesus existing was to get crucified in the first place. Basically, God sacrificing himself to himself to appease himself in order to save us all from himself.
Disclaimer: I'm not an expert in early Christianity.
If you wanted to be a pedantic asshole you could argue that the Jewish authorities were technically responsible because they turned Jesus in to the authorities, but the Romans were the ones who actually carried out the execution. Jesus also posed a threat to the Romans because he preached against the Roman occupation of Judea and thus the Romans would have had a reason to execute him. There were a ton of Jewish sects and messiah claimants at the time and the Jews didn't go around executing everyone who disagreed with them. The "Jews killed Jesus" canard came about around the time Christianity started gaining popularity with gentiles, so I'm guessing we can blame Paul for this.
Then again, we're trying to apply logic to a flyer made by someone who thinks serial killers are part of an occult conspiracy to the goddess Ceres, Germans are persecuted, Jewish people worship the Holocaust and are trying to push "Holocaustianity" on everyone, and that Mel Gibson sold out to the Jews (among other insane things). "Jews killed Jesus" is probably the least ridiculous thing he believes.
