You are fallaciously conflating a mathematical model with your own personal metaphysical interpretation of what the model represents. You are presupposing that a purely mathematical description in terms of a superposition of basis states literally represents, in ontological reality, particles being in multiple states at once, and then when I say I disagree with that metaphysical accounting, you accuse me of denying the physics.

But I am not. I am denying your philosophical accounting of the physics. Nothing about a superposition of basis states implies that particles are in multiple states at once. Do not conflate a mathematical description (superposition) with a specific metaphysical ontology, and don’t accuse others of being science deniers because they disagree with your metaphysics. I do not appreciate that at all.
