Aside from the potential results of comparing major and regional accident/incident rates, which is probably a point you don't want to make anyway, what exactly do you hope to gain by throwing stones like that?

While isolated exceptions abound, the fact of the matter is the entry level major pilot is, on average, significantly more experienced than the entry level regional pilot. Anyone can, and does, make mistakes. Its not only easier, its way easier to get on with a regional than it is a major. That said, there are great pilots at both. But you're not seriously trying to imply there is zero difference *on average* are you?
