I doubt that the UN will successfully ban religion. There are many countries with official religions these days, and they would start a riot if they banned religion. And I doubt, with all the legal doubletalk by the Watchtower Society, that they will be banned either.
Instead of banning religion, they should expose it. When people see the fully integrated facts, they see how much of religion is a smokescreen. And that goes double for the Watchtower Society, since they not only are based on a Bible that glorifies a value-destroying God, but they don't even follow it as they claim.
