I think where you can see contempt, is in the characterization that the internet breeds a certain sense of humour and that it's an objectively bad one. Irony is not unique to the internet, nor is self-deprecating humour, or cynical humour, or are slang words. Usually when you hear an internet-slang used in real life it's a reference, not an earnest attempt to use the word legitimately. Like when people reference TV shows or movies, you've have to have seen it to enjoy the reference. If using it works for your in-group then that's great, you all understand eachother.
