Because people who tend to disbelieve in such things tend to believe morbid things that aren't supernatural, or even natural. Abortion being good, despite murder of a being whose DNA isn't the mother's, therefore isn't part of her body. Transgenderism being normal, despite continued research (particularly from Johns Hopkins in the US) that gender dysphoria is a mental disorder that is harmful, like other mental disorders, if not treated. Belief that government is good, despite government being made of people...and people being inherently flawed. Humanism, the belief that people are God, despite human nature's flaws. These are so worldly, and all beliefs in unnknowledge.
