The fact of the matter is, religion in general is a completely outdated system which is simply doesn't belong in 21st century anymore, it's just incompatible with our modern values and morals.
Perhaps back in the days when there was no concept of nation states with well defined laws and constitutions it was a in fact, necessary evil to keep the people united (and keep us from killing and raping the fuckk outta each other, although to what extent they succeeded in meeting this objective, if it was one of the objectives at all, remains debatable at best), and also, to try and answer various questions wrt to various natural phenomena, since our understanding of science was rudimentary at best.
But now, at this age and time, when science has made so much progress and our knowledge base continues to grow and getting enrich by leaps and bounds (heck the human race is now on the verge of creating artificial organic life forms or truly "playing god" as the saying goes) and above all, when we've got the nation states to keep us united, there is just reason left for religions to be around.
But since it ain't going anywhere, not in the near foreseeable future at least, we'll continue to remain divided and segregated and also killing each other off.Just my two cents.
