I think the problem here is that Louis CK has a very devoted fan following, and very devoted fan followings like to justify the actions of the person they’re devoted to.
And that’s fine. I totally get that. Hell, I’ve DONE that on several occasions.
Where it becomes less-fine is when the crux of a joke relies on the idea that sexual harassment is funny, and doesn’t do all that much to disprove it; I haven’t seen the episode, but allegedly he looks like a moron/childish/whatever for the rest of it for getting worked up. I want to know why the point couldn’t have been made without normalizing harassment.
Asking that question is sure to piss people off, though. As it already has. Woo!
