Well, the problem is this is an online forum... Anybody can get away saying anything or offending others. In real life, these members won't have the courage to even look at each other in an untoward way. Even if you argue by facts/logic, personal attack will start sooner or later and make debating impossible. Especially, i notice, Arabian members tend to be very emotional. While Iranian members tend to be use a "slapstick" approach to argument
