I had to look up shock comedy to see what it was.
For me, it depends on what the subject is. Usually if it is something sexual or toilet humor, I'm ok with it. But if there is gore, or if you're making fun of someone who is hurt by the humor, I am not ok with it. Family Guy has shock humor and I am half and half with that show. I laugh a LOT at Peter Griffin. But there's also a lot in it that I find not only completely unfunny, but repulsive. It's pathetic.
