Keep it civil: Don't engage in personal attacks, name-calling, or blanket generalizations in your discussions. Say how you feel or what you think, but be careful about ascribing motives to the actions of others or telling others how they "should" think. People seeking to engage and discuss will find themselves asking questions, seeking clarifications, and describing their own opinion. People seeking to "win an argument" sometimes end up taking cheap shots, calling people names, and generally trying to indimidate others. My advice: don't try to win. You've probably heard the adage that nobody ever wins an argument on the internet.
