Butts are srs bsnis. The touching thereof in particular.
What I am emotionally invested in is the frankly offensive notion of imposing limitations on other people's perfectly normal speech because a minority find something objectionable, when said minority are the ones who can with minimal effort avoid being subjected to whatever they're offended by through a veritable cornucopia of means, including but not limited to; word replacement addons, closing the tab, various internet filters etc etc.
There is speech that is offensive enough to warrant being ousted from various communities, depending on the openness of the media/forum in question but this is honestly so flat out silly that I am quite honestly offended by it. It implies that there is some sort of right not to be offended, no matter what you might personally find offensive, which is a horrifying idea in and of itself.
To quote a rather eloquent australian, I find boybands offensive. If I was to demand the censure of that subject from a public forum I'd be laughed out if not outright banned.
In short, finding something offensive becomes -your- personal problem to deal with (multiple solutions already supplied) unless it's sufficiently outrageous that the community at large stands together against it, like slurs based on gender or sexuality for instance.
