> This is why Islam can never be subject to a meaningful "reformation": unlike Christianity, where Sola Scriptura dragged the church back onto a MORE peaceful, tolerant (after a time) and LESS abusive path

I don't think that there is any plausible argument that "Sola Scriptura" did that (the Protestant Reformation may ultimately have, but not so much because of its theology -- and certain not the particular doctrine of Sola Scriptura, but by triggering a series of international and civil wars which in the long term forced governments to give up most direct enforcement of sectarian religious rules, even if they retained an established church, in order to maintain civil order.)
