While I rarely delve into subjects pertaining to apologetics and philosophy, I will say this about "materialism" or "material monism": its proponents do not necessarily deny the existence of minds or ideas. They will say, however, that matter is metaphysically superior to these ideas and give rise to them through interaction. Thoughts, for example, are the product of electrical impulses in the brain.
I would ask someone saying this to prove it, since the burden of proof is on his shoulders. To say that matter can spawn something that is beyond itself and its existence is quite a claim that requires extraordinary evidence.
