A Materialist's Misgivings About Eliminative Materialism

I‘m a materialist, and not too embarassed about it. It would be nice to have a knock down argument to defend materialism, but not having one, I instinctively fight off idealists, dualists, skeptics, or whatever, with the same punches and feints used by materialists from time immemorial. Like, say, the snide observation that a material like liquor gets even my idealist friends drunk, or that the senile dualists I have known don't seem at all to consist of ageless minds trapped in aging bodies. I will not resort to ad baculum, because all non-materialists I‘ve known, of whatever stripe, act as though tampering with their bodies is the same as tampering with their very selves.
