Politically Incorrect Characters?

[kshRox]

I'll admit in public that I love South Park. It still makes me laugh, and one of the reasons is that they are "equal-opportunity" offenders. One of my WIPs has a main character who is like this. He say offensive thing and is pretty selfish, which is one of his flaws, but I want him to be sympathetic a well.

What's your threshold for offensive humor? Killing obviously doesn't offend too many people these days, but you say things about kids, women, the elderly, an obese or metally disabled person (or someone who is both) and well... that can still ruffle some feathers. So I'm trying to define the line.

What do you think? What is excusable, permissible, or even enjoyable?

I think the point of an intentionally anti-PC character is to specifically lampoon those sacred cows you mention.
