Wait, do materialists accept both that consciousness (in the sense of sense informally and very much nonmaterially stated as “experiencing qualia”, as opposed to the medical sense which is clearly a defined material state) exists and has a single accepted coherent materialistic definition that can could be applied here?

Because it's always seemed to me that “if you are a materialist, you probably think conscious is an interesting fuzzy idea that would be interesting to explore if it could be adequately defined to make that possible, which it clearly hasn't and doesn't seem likely to ever be” is more accurate.
