One only has to read these forums to see that aviation is full of opinionated ego heads, folks quick to point the bone and only too happy to spread innunendo, gossip and plain untruths about their fellow pilots. GA has never been able to acheive consensus on anything and has always been full of quick to judge then execute individuals.
My question is why are you so surprised when CASA use the same tactics? CASA are nothing more than a reflection of the industry they serve.
