In one of my more important videos ever made (originally uploaded in 2011*, but, even though I could have done a better job, I personally think it's one of my greatest videos on religion), I explained how religion is not useful in spreading peace and, in fact, is inherently detrimental to the very concept of peace. Using examples from figures such as Sam Harris and Christopher Hitchens, I also dwelt into how calling Islam a "religion of peace" is a horrible idea, and deal with the youtube user Dawahfilms and his claims on enlightenment having horrible ramifications on humanity, when in fact, it's actually brought more good for society.
As always, please rate, favorite, share and comment on this video, as I feel it's one of the best videos I've ever done.
*Yeah, I know. It was 2011, and I didn't have the best microphone at the time compared to today. There's a lot more I could possibly have said on the subject, but, unless I do another video at another time, I'm content with what I've said here.
