Ok i still haven't properly looked at the links due to a lack of spoons but in an ideal world i'm enough of a hippy to want to have this discussion with the people who say it! But mostly i'm not going to because it useing the phrase is usually an alarm bell that the speaker is a nutjob (as a person with mental health problems myself i did try to think of an lterntive wording for nutjob but nothing else seems to fit quite so well!)
