You would need to account for levels of activity before anyone can make comparisons of GA and RAA accident rates.
Then there is the question of certified vs. uncertified aircraft.
Deal with those before making wild statements about the RAA.
Then there is the question of the Aristocratic principle. It is easier for a complete idiot to buy a trike - by definition the idiot can’t make enough money to buy a Bonanza. So what do you expect to have the higher accident rate? Unfortunately I have recent tragic experience of this in action.
A corollary to that is that if you make flying expensive enough, there will be fewer accidents of any sort.
I fail to see any factual base to statements like “GA is safer”, etc. etc.
I don’t think RAA pilots value their lives any less than GA pilots and I cannot think of any training difference that would automatically result in a higher accident rate. As Squawk implied , the basics are pretty simple.
To put that another way, I do not consider my training as a GA pilot makes me somehow safer than a similarly motivated RAA pilot.
