Exactly. Countless other religions are also false, but do not threaten anyone.
I don't know about that... even so-called peaceful Buddhists go on murderous rampages in India in the name of Buddhism. If you can find justification to kill in Buddhism, which seems to be built around a fat, stoned-looking guy, I'd say there's probably no religion that can't be hammered into a sword. And socialism and communism are religions of a sort, they have prophets, manifestos, primary texts...
