More to the question....
Aside from things like child porn, and mutilated bodies...is there any speech or pictures that are so egregious that they will warp the minds and irreparably damage all the cupcakes and snowflakes out there?
Sheesh people..grow some skin.
Offensive speech and expression, and things controversial are exactly what needs to be allowed and protected...even by companies like this...if people actually depends on these sites for news and info (I still can't imagine this, but apparently so)...then you need to allow a full fun spigot flow of stuff to go through, just so people don't get complacent and thing the world is a warm and fuzzy place.
I think if more controversial stuff was disseminated you'd not see people freaking out so badly when something offensive-nature some how accidentally gets published or expressed.
Seeing a naked hoo-hoo, or hearing a deragatory term (honky, chink, nig-g-er, spic, etc) (NOTE: When did slashdot put in a lameness filter on words here like these??? Did I just seriously have to put symbols into a word, that's new!! The other ones are ok, but this one isn't?) , or an image of some religious figure....is NOT the end of the world and it won't destroy the world.
On the contrary, let it be said and expressed, and soon, it won't be perceived as such a big deal.
Its kinda like how kids in the US are kept so far away from a simple thing like alcohol thoughout child hood....its a "forbidden fruit"..and when they leave the house, they binge on it, etc.
Same thing with offensive expression....if you make it the forbidden fruit, well....people go apeshit over things that really shouldn't occupy ones attention for more than a passing glance.
