j3pipercub, what exactly was it in the article that you didn't like? You've already said you don't believe the risk mitigation angle and had someone politely explain to you what risk mitigation is. From there you should be able to see that everything those pilots do is mitigating the risk associated with low level aerobatics. The only additional thing they could do would be to not participate, but that wouldn't be risk mitigation, that would be risk avoidance. You are correct that you're entitled to an opinion, but an opinion can still be flat out wrong and an opinion based on ignorance is worthless. Many people have no interest in listening to worthless opinions.
