It seems to me that there could be some serious confusion here, mixing things together which just don’t belong together. Of course it is absolutely essential, from the viewpoint of personal development and peace of mind and life improvement, that we learn to understand that how we think about things is massively important. It is one enormous leap from that to some kind of woolly well-intentioned statement about bad guys existing in our minds and attitudes, as if we — the ordinary decent law-abiding citizens — had anything to do with, or should not have to have tough and practical ways of dealing with, people destroying ancient monuments and beheading aid workers and ethnic cleansing in the Balkans and oppression and starvation in North Korea and the ridiculous macho posturings of, say, Putin. Or, say, Trump. The bad guys really are out there, as well as us having the obligation of civilisation to understand how humans get damaged by social and emotional environments, and to help them where possible. As long as they’re not trying to kill us first of course. If you’re lying in a gutter bleeding to death you ain’t never gonna be in any position to help anybody ever again.
