It isn't motivated politically. It just seems to be true and declaring them toxic seems like an error.

Anyway, give me a better explanation why people don't look like they did only a few decades ago.

Are you talking about the obesity epidemic? There was a recent paper discussed on HN talking about how it was probably an environmental change, but I don’t think they mentioned heavy metals. I think they mentioned plastics and lithium as possibilities. Was lead widespread in the environment before the 20th century? I don’t remember pre-20th century photographs showing widespread obesity.
