Do what thou wilt shall be the whole of the Law,
"Religion causes more war than anything. "
Prove it. This is a talking point often iterated, but is not backed up by any academic study. In fact, the only scholarly estimate I ave ever found places it at 7%. Even allowing for error, that is nowhere near 51%.
"The crusades were terrible."
The Crusades were not about religion. The first was a result of the Pope being asked for help by Constantinople. You should probably read a history book. Even the reclaiming of Jerusalem was very little to do with religions.
" If there was no religion on earth, we could all focus on the now and the future of OUR planet ."
I highly doubt that. Good numbers of people do not kill each other simply because they share a religion. The removal of religion would be about the worst step possible for global diplomacy. Unless, of course, you feel the removal of religion should also entail thinking exactly as you do. But that's absurd.
Love is the law, love under Will.
