Why are people so much ruder on here than they would be in real life?

Type has no emotion.... I don't think people are being rude, well some are, but most are just answering questions as they see fit to answer them.... Quick and to the point.... People fuss if you get to LONG winded in here..... ROFL... So MOST keep it short..... Might look rude, but really not meant to be...... go in peace.... God bless
