Because at some point, we have to be able to collectively have a sense of humor about sensitive topics again. It can't ALWAYS be perfectly PC. And there's a growing backlash to the incessant "perfectly PC or else" dialogue that ultimately causes generally liberal people to move to the center because they get tired of being beat over the head with every little thing. It's like when I was a vegetarian in my late teens. It wasn't good enough for my vegan friends, who weren't good enough for monks that sweep in front of themselves to avoid killing bugs, etc. At some point, in some situations, a certain level of inappropriateness has to be ok if there is no intent to harm. Because otherwise, we're all spending our lives sweeping for fucking bugs. It's unreasonable, and counterproductive.
