I remember learning about the title change, and the reason, and thinking “I know what a philosophers stone is…” because I’d come across it in my nerdy reading somewhere. I didn’t think American children would have had a problem with it. I’m kind of offended that publishers, television and movie producers, record executives, etc keep pulling this kind of garbage. We aren’t stupid, and I’m willing to bet that more often than not people are willing rise to the intelligence of a work rather than shy away from it.
