Sarcasm and arrogance are two different things. If one is called arrogant because they moderate someone ... because they are in the position to tell someone contrary to what someone else thinks ... then arrogant I am. If one is arrogant because he stands on firm ground and argues that ground, then anyone with a firm opinions must be arrogant. People need to redefine arrogance and see where it really fits. Sarcasm is on a different caboose as that of arrogance. One will only take offense from sarcasm if they do not understand it because they are incapable of understanding it or because of ammm ... errr ... arrogance. Hence heated arguments and "unwanted impression" will ensue. To think that this can be avoided in a forum where only the most firm believer in their stand will prevail is foolish.
