Rational Fundamentalism is a form of secular fundamentalism that's full based on rationalism, it seeks on the use of the philosophy of rationalism and positivism in order to justify secular fundamentalism and atheist fundamentalism as well, often calling religious, spiritual, extraphysical, supernatural and immaterial beliefs as "irrational" and fighting them anywhere and all the time. A good example of rational fundamentalism is rational imperialism, that takes rational fundamentalism into a way that all kinds of religious, spiritual, extraphysical, supernatural and immaterial beliefs, also including feelings and empathy, must be countered and everyone must follow rationalism, scientism, positivism and physicalism as its main beliefs.
"Rational Fundamentalism and Rational Imperialism are really common nowadays, they only show about how can rationalism, new atheism, anti-theism, materialism, physicalism, scientism and positivism so violent and aggressive nowadays, and how they all are no different from religious fundamentalism and of those who they call as "irrational"."
