Hint: saying that believers are that way because they're scared of what will happen if they're not is not this. I mean, I guess it's condescending rather than belittling, if you want to split hairs. You have some very stereotypical beliefs about what religion and the religious are actually like. It's also a wildly arrogant viewpoint on your part. "People would agree with me if only they could understand my view of the world, but they can't, because they're too stuck in their culture." Remember that the people who're loudest about their beliefs aren't typically representative.free them rather than belittling them
What people who believe lack is only the culture and settings required to eeke them out of their views and into a place where they are comfortable exploring and changing the views that they hold.
