I think I have read most of what has been mentioned her so far.
The most recent book I have read that most people here would find controversial is Deep Green Resistance Aric McBay, Lierre Keith, and Derrick Jensen. It is sort of like a Communist Manifesto for Greens and calls for nothing less than the destruction of industrial civilization itself. This destruction is presented as the only alternative to a complete collapse in the ecology and the extinction of many species, including the human race. It is rather casually mentioned that this would require the human population to be reduced to around 500-600 million (90%+ reduction).
DGR specifically calls for attacks on infrastructure including oil refineries, coal mines, gas wells, communications towers, and nuclear reactors. It is somewhat less direct about killing guards, police, military personnel, and politicians but the tenor of the argument is very extreme. It is a preview of coming attractions and scary.
