Kossef's hypocrisy

I am not Jewish, nor am I a religious zealot, but I found what the Gavin Kossef character was doing to be so revolting! I guess he's Jewish by birth, but all that pretense, singing Hebrew to the kids (not for the kids mind you, just means to an end so he could get the reference letter), practicing the prayers, wearing the yarmulke. He's a self-proclaimed Atheist and find it so offensive that he would "play the Jewish card" merely to get citizenship. It would be one thing if we could see his character embracing the religion after some sort of epiphany or if he had actually learned something from his "cramming", but I get the sense that he never will take it seriously. And poor Jewish teacher at the end...she's smitten and has no clue about his hypocrisy. I think he only keeps his job at the Jewish school just to maintain the facade, in case the immigration officials are watching him. He literally just made me ill! I think what he did was far worse than the Australian girl prostituting herself..at least her shame doesn't involve religion.
