Thanks to you for the welcome comment!
In these days, scientism (under the showy pretence of rationalism) is too often used like a cudgel to impose “the right thoughts” and “the right way of thinking” to people. The rule of thumb is: never trust blindly whoever says “I am rational, so you must believe me!”. Rationality is an observable, so you must analyze what has been said, disregarding completely the claim “I am rational”: if he really is, his words will speak in favor of that claim.
