According to Ari Lesser's Facebook page, he's a rapper, reggae singer and spoken word artist from Cleveland, Ohio.
In this song he talks about if you're going to boycott Israel, then you better boycott all the nations of the world with major human rights violations. I don't agree with a few of his examples, but it's a clever song. And he has a point. Not that it will make one whit of a difference to the BDS (Boycott Israel) movement.
