Did religious folks help? Of course.
Yes, but not as much as they hurt. I still encounter Christians today who are certain that dinosaur bones were put in place by lawyers and the devil or that the world is only thousands of years old.
Would progress in science have been faster if all the contributors were anti-religion?
Quite likely.
Ok - what non-religious country in the past one thousand years do you feel pushed/allowed science to advance better than the Christian countries? You encounter some Christians that don't believe in evolution and decide that this is a common theme. This is as fair as taking 2000 years of history and only citing examples where the churches hindered science. This shows how close minded you are.
If I pointed to non-Christian or godless countries and pointed out their human rights records, would that prove anything to you? If I told you I knew some really hate-filled, intolerant atheists, would that prove something to you? I doubt it, just like you knowing some ignorant people does mean anything to me.
I sincerely hope that the anti-religious folks keep pushing harder and harder against people that have faith. Eventually, you are going to push people to the point where they start speaking up for themselves.
