Sorry, Colophon, but with content such as “It cannot be disputed (although I’m sure some will try)” the OP was not provocative, it was needlessly antagonistic. With that language you run the risk of ab initio excluding from participation in the thread anyone who does not agree with you on the desirability of the extinction of religion, or the reasons (which you only mention generically and glancingly as if already established as axioms) why that’s desirable.
Or, as you noticed, of attracting to it those who will call you up on the gall and arrogance of holding up your position as an established premise.
Now you’re gonna have the thread fill up with people throwing in arguments, examples and couterarguments and counterexamples of how religion HAS been beneficial or HAS been deleterious (at best) or how you are or are not craniorectally inverted (at worst) as opposed to the “begged question” in your OP, which is if “killing off religion” is even a viable possibility, never mind a desirable one.
In any case…
… even among those who would subscribe to the basic OP POV on “religion” itself, there are many who will tell you that if anything, you are talking about “killing off” A noxious form of “religion”, BUT, they could argue, that form of “religion” may just as well be simply supplanted by another form of “idolatry”, be it of ideology, nation, “race”, class, gender, your taste in cheeses, what have you, that will interfere just as much with your vision of how a mature species should behave. There will be those who argue that the need for a structured belief-system that seeks a “meaning” to existence, to be found above and beyond yourself, is an adaptive trait of of the evolution of human society or even an emergent trait of the evolution of the brain’s consciousness itself, so you will never be rid of something that fulfills the sociological/anthopological role of religion right up to and including faithful adherence to teachings (v. followers fo Ayn Rand)
And of course, the extinction of that pernicious form of “religion” need not require the “killing off” of the entirety of that socio/anthropological phenomenon.
