Perhaps we should all start assuming that any blunt, snarky comment is really meant as a piss-take. E.g., if you read "Apple is a bunch of blatant design thieves", assume that no one could intend that at face value, so it's really facetious joking meant to express the opposite.
We'll all feel a lot better, and the blunt and snarky will realize that their posts are having the reverse effect expected.
Because most people don't have the ability to write clearly enough to express their intent, and also because there are so many literal minded people out there. Labels and smileys serve the same purpose as laugh tracks on TV programmes, they tell the stupid how to react.
