It's something that was studied and analyzed by millions of experts: there were lies, those lies built stuff (and by stuff I don't mean a house or a church or a castle, I mean civilizations) and we onlye benefited from them (mostly on the long term, since probably some people were killed because they were a risk or a billion other reasons). That's it. Why am I getting this answer? I don't deny that. I'm Catholic, but I'm not blind and I'm completely aware that the Church as an intistution probably made more harm then good in its existence. But really, why am I getting this? Because I mentioned religious extremists? But that's true! So true in fact that so far that part of the discussion (the all point of it) was avoided in favor of other unrelated stuff (not directing this part at you). Wars today are all related to: fascism, religious extremists and financial interests. I never at any point said we would be a big happy family if religion, fascims and capitalism didn't exist.
