Its just that sarcasm cant be read through type unless you make it painfully obvious, losing the point. Its hard to read sarcasm, and then throw in the trolls, who stay stupid/ignorant things on a daily basis just to get people angry, and most people just have trouble telling if its sarcasm, trolling, or idiocy. Its not our fault as americans, because et me say, that in real life we are usually all quite sarcastic. Im just going ot take trolls as a more american thing, and say that it makes us a bit mre confused than others.
