That depends...are we talking about Christianity as it is practiced today, where Christians leave others of different faiths alone in peace? Or are we talking about the Christianity that was practiced in Europe between three and five hundred years ago, when people did unspeakable things to their fellow man over the 'crime' of heresy.
No, it doesn't depend. Those who did those despicable things in the name of Christianity weren't real Christians. A Christian is a *little Christ*. Those horrors go completely contrary to the teachings of Christ, so no, those who practiced them were not Christians.
Just like your example of atheists and the "Perez Hiltons" of atheism, so with the atrocities perpetrated in the name of Christianity. People will use anything as an excuse to justify their behavior. If religion works, they'll use that. If something else works, they'll use that.
It doesn't mean the Christianity is to blame.
Agreed, it means that the interpretation of that Christianity is to blame.
I prefer the milder versions of today, thank you. Although I still have bad memories of nuns with rulers...
I should have added you to 228 too :-)
