I think you need to lay the hell off everybody, jackass...
:-D Joking, for those unable to 'get it'.
Eventually one side runs out of arguments, but doesn't want to give up the argument, so they start personal attacks (and with some discussions, this happens around the second post, in cases where the original point is so completely lame and stupid that it can't be defended). Once that starts, the opposing side often feels the need to retaliate in kind, but often they continue real argument, which just makes the 1st person look even worse.
The same thing does happen in real life, it just doesn't get quite so heated and such strong insults aren't often used. When they are, usually gunplay occurs.
