A last trick is to become personal, insulting and rude as soon as you perceive that your opponent has the upper hand. In becoming personal you leave the subject altogether, and turn your attack on the person by remarks of an offensive and spiteful character. This is a very popular trick, because everyone is able to carry it into effect.
But the thing is, there are at least 37 options before that one and it's certainly not worth making enemies over a game to do so. That's why we try to keep our cool and not go down that path.
But here's what you can expect: your words are going to be torn apart and taken out of context. You are going to be called a liar.
You need to expect these things because that's what the bad guys do. It's what the good guys are looking for and going to accuse you of doing. It's on you to argue that your words are being twisted. It's on you to prove you are telling the truth.
On behalf of all members of this forum, I beseech you: Don't get discouraged and think we're insulting you. Because it isn't personal.
