Well, you and I will just have to disagree on this point. Statistics and stupid pilot tricks aside, a look at the engineering is all you have to do. Possibly due to regulation, or possibly due to liability exposure, or both, certified plane makers design and engineer their aircraft with safety as one of the foremost design criteria. With E/AB, safety is basically an after thought. First and foremost for them is low cost, light weight and easy to build.
You are correct that most E/AB accidents seem to be due to poor piloting, questionable construction, or design and well, people experimenting, but side by side sitting on the ramp, the certified airplane is just a safer airplane because of all the work that went into to try to compensate for bad piloting and also when things do go totally wrong, trying to protect the occupants. This makes the certified airplane heavier, slower, more expensive and a lot harder to build.
Try this next time when you're at Oshkosh- Ask the Vans guys if they ever thought about certifying any of their planes (beyond the quasi- sort of certification of the LSA RV-12). When they stop laughing and giving you in no uncertain term, "Hell no!", ask them what it would take to certify one of their planes. Their answer will be, basically start over and design a whole different airplane. I know, I have asked this question to them... twice and with the same result. These are people that are very close to the RV design and know aviation and in their opinion the Vans RV- anything is uncertifiable.
Certification is ALL about safety and nothing else. This tells me the certified airplane is safer than the uncertified airplane as logic would dictate.
