If you see the actual video, he doesn't look smart or witty, he just looks like an *** and loud for no reason. If it were a debate, he'd look like he was panicking and desperate as ***.
Also, the girl, eventhough an orthodox possibly annoying christian, was really nice and calm about the whole thing. Louis CK screaming at an inoffensive girl made him look like an even bigger ***.

I've seen the gif on HL, but I can't remember if the title was similar.
If someone goes as far as to link it, I will delete it.
