in an argument don't leave any wriggle room, once you have found a weakness in your opponents' argument, use that weakness and destroy his credibility, after that, stop responding to his or her bullshit defenses because all their defending ever does is show how insecure they are about their lies and that their bullshit truly is bullshit, ignoring a person and saying nothing is sometimes the best way to say the most. let your retarded "opponent" talk for you.
