Buddhists don't kill people in the name of their religion. If fact the buddhists neighbors I have are great.
Not much to fear from Buddhists. They don't fly planeloads of people into occupied buildings, blow up subways or go on mass murder rampages.
Buddhists do indeed have a religion of peace.
No, sick people of ANY faith do all that you described. They blow up Olympic parks, Federal Buildings and feed children poisoned Kool-Aid too...
And I remember a Buddhist or two, or three setting themselves on fire to protest the Vietnam conflict.
But learning about each other is never a bad thing, as Schoolhouse Rock always said "Knowledge is Power".
