Nothing pseudo about it. The artifacts have come from legitimate digs. It's the conclusions that are off, not the dating.
Rick touched on this earlier. It's the fear of the Other--the ones who are like Us, but not Us. Underlying it is a fear that if they are too much like Us, then we cease to be unique, special, even sacred. It's disturbing to many people, too many, really. If Neanderthals have art, then they are no longer really Others--they must be Us. And we've set AMH on a pedestal so high that the mere thought of our Neanderthal brethren joining us is enough to give some people vapors and conniptions.
