Wow. Quite the brutal comment, I find it hard to disagree. Muslims overwhelming silence on radicalism speaks volumes. No doubt many of the Ts would think your analysis is dead on. Your thought is worth more exploration.
If I may ask, were you raised, or are now, Roman Catholic. The reason I ask is that from my perspective, despite its bloody beginnings the Reformation was a very good thing. Until you brought this up, the concept of a dark Reformation simply never occurred to me.
I like your phrase 'dark reformation'. I was raised Protestant, thought not a terribly observant one. Anymore I just say I'm Christian. (Still not very observant and I don't claim that's a good thing.)
