I am very certain that within the next 20 years democratic-republic and socialized countries (of which the people have the right to vote for who will rule them) which have elections run in a democratic way, will not try to destroy all religion or even some religions. I don't even believe Islamic countries will try that. I have told my JW mom and JW sister those views. They disagree with me but I have them.
There are simply too many people in countries which are in some sense democracies for the governments to try to destroy all religions. It is even hard for me to imagine that in 30 years from now such types of countries will try to do such, despite the rapidly rising percentage of people in the USA who claim to have no religion.
I certainly can't believe that an international coalition of all countries of the world (or even of all countries comprising the UN) would attempt to do destroy all religions (or even replace it with a government created religion) within 40 years. I have told my mom and sister that also.
