Wow, it's so impossibly hard to pick from that list! That and each of them really perpetrate different aspects of offensiveness. Texting was probably the initial evil by completely tossing grammar to the side of the road, driving backwards over it. But that was due to necessity considering how short texts had to be. Abbreviating words like "you" and "are" wasn't too bad. I will defend my vote of YouTube because a good 99% of those posts are just jaw-droppingly offensive. A great majority of those bad posts are textish type messages. No grammer to be found within a hundred miles. But they take it a step further in the fact that every post consists of two equally awful choices. Either "that wuz so awsum!! ROFL!!!1!" or "taht wuz gayz! u r gay n ur mom is gay." Either blind appreciation so as not to rock the boat or constant irrelevant berating using sexual slurs.
