Oh, so were talking "in terms of history" then? History of what? The world? Religion? Modern politics? I guess that's convenient for you. But since this is/was a discussion of US politics, and this country is only 200+ yrs old, I'd say that it wouldn't really have much bearing. But then again, why should that ever stop anybody that has to grasp at straws to make their point?
Religion has a bloody and reprehensible history. Good luck turning your nose up at other religions, like they're the bloodthirsty ones. The only thing that stops religion from being bloodthristy is when it gets marginalized, like Christianity today - where most people could give a fuck, they're just like "oh I'm Christian and got dirt rubbed on my head today." Give muslims some time, they'll get there.
