if you notice... Must of them are either sensored or filtered to a comepletely different word. MODs have the power to bypass the filter. Words like damn, ass, and he'll don't get filtered out because they really aren't that inappropriate. this sight was meant for people 13y/o and up making it a pg13 site. Just like in movies, that means there will be profanity. Judging by your question, I'm assuming you are younger than 13 thus not actually suppose to be on this site. In that case just ignore the naughty words.
But really this here's 'Merica and we can f*ckin cuss if we want to.
