Believing in dull, barren, soul-dead Scientific Materialism is everyone's right, but

46. No, he means Scientific Materialism

Materialism, in this context, does not mean what you say. Perhaps this misunderstanding is why so many people are declaring their opposition to scientific materialism recently.

The OP is talking about the philosophical position that the world consists only of natural elements, no ghosts, spirits, gods, or other supernatural elements. Most theists, like Christians, inherently disagree with the most extreme form of this notion but they still might (and usually do on this side of the aisle) agree with a more moderate conception of this idea, where they act as if they live in a scientific materialist world and make special exceptions for their spiritual beliefs as needed, like belief in an afterlife.

The most contentious of the issues between scientific materialism and opposing views is the characteristic of the mind. Simply, scientific materialism says the mind is a function of the physical body. Opposing views say there's a soul, or similar, that exists apart from the physical body that is required for a mind to exist.
