Well, if an undercover cops manages to instigate you to do something illegal, the underlying desire to do it must have already been there, otherwise you’d just tell him to fuck off. But entrapment is still illegal because if he hadn’t provided you with a chance to do it, you may not have followed through after all.

What you seem to be saying is “entrapment is fine as long as it’s done to people I hate”.

You’re missing the point. He deliberately encouraged people to express antisemitism and now he’s complaining that people are expressing more antisemitism.

Yeah, you could argue that he was only making a joke or a political statement about latent antisemitism that was already present in society, but if he were the police (and he kinda IS policing antisemitism now), this would be called entrapment.

More recently though, he has spent his time complaining about the rise of antisemitism when he himself has done a fair amount of work contributing to it while in the character of Borat.
