There are two conversations to be had on the recent tosh topic. One is whether a rape joke is ok or not and the other is whether it is ok to heckle or not. Obviously one is making more noise than the other.
A rape joke is debatable though and it has the opportunity of making the comedian looking like an ass and the girl sympathetic. However it’s generally always wrong to heckle, so boring. The original blog of this issue marginalized that as such along with comedians in general. It opened focused on the girls, focused on their story, set everyone up and described tosh as amateur and awkward (though from what I understood his act is an intentionally awkward white guy telling offensive jokes) and easily dismissed. Everyone else is a side character from the main point of view. Tosh tried turning down the heckler originally, acknowledged the lack of context in the story, and finally pulled a “fine, you’re right, I’m sorry” move and here Louis CK shows why that was going to fail.
