Empire Of The Summer Moon Gwynne, S. C.
This book has cemented my belief that the most toxic substance on Earth may well be European testosterone. We(I am of English descent) have destroyed the indigenous cultures in the USA, and pretty much used religion as justification, i.e. Manifest Destiny. It appears that wherever European explorers ventured, they pretty much did as they pleased with the populace because they could, and they had God on their side. Mixing Caucasian testosterone and religion produces a compound that makes nuclear waste seem almost inert.
