Did I actually say any of that?
I'm sure there are religious people who would be labeled "smart" by most or are even much more intelligent than I am on a certain subject matter, but I'm also sure you'll lose that bet. Of course there are moronic atheists, people who are just following an idol or trend. What I'm saying is that there's a negative correlation between intelligence and religion (there are studies corroborating this claim and it's also my overwhelming personal experience within academia). The problem isn't that these people can't think logically or critically about something, it's that they lose all of their logical intellect as soon as the subject goes anywhere near their religious beliefs. And that's a BIG problem.
Of course I know Lemaître, the man who first proposed the idea of an expanding universe, was part priest. Being a Belgian physicist myself, he’s part of my national history as well as my educational background. I assume you’ve just heard that “the guy who proposed the Big Bang Theory was a priest” - that’s usually the case anyway, I apologize if it isn’t. In any case you shouldn’t use that argument, since firstly a single case makes for horrible statistics, especially when I can name dozens of his contemporaries who made equally large contributions to science but were not religious. Secondly, many natural philosophers in the “earlier” days of science were actually men of the Church, because those were the people with the best access to knowledge and sufficient free time and money to take up the hobby. Although Lemaître was part of a generation when science was starting to become a viable job to earn a living off (mind you, even Feynman still had financial trouble in the beginning of his career), a religious title was still very much required to become a professor at the University of Leuven. That doesn’t mean he wasn’t actually religious, obviously, but he was definitely also a product of his time. How many priests are at the frontiers of science today?
Lack of education undoubtedly IS the big problem. Hatred is a problem as well, but it’s an effect of uneducated views and should diminish with increased levels of education, since this implies increased understanding, and it's much more difficult to hate something you have a deep, thorough, nuanced understanding of.
