Ego is your friend. He makes you reflect on your systems and practices. The fact that for the most part your replies are rational rather than emotive shows how effective his strategy is. He is helping the cause of Southern Kung-Fu (howsoever defined) because he gives attention to many good systems and prompts strong helpful responses from their representatives. He should be encouraged not shunned. If he gave ‘attention’ to Northern Kung-Fu in the same way, he would help them too - allow the practitioners to show their knowledge and skill as well as good martial arts manners. He is your good friend… don’t ignore him.
