The world is full of lots of people play acting and hurling stuff about, unconscious of the effects. And there are large group karmic things going on through history that none of us should ever take personally. Rushing about trying to rectify the sins of the past is not productive. The best you can do is to be present as the new you in the now, holding your light as a steady candle to add to the beam of calm and love now spreading to help wake more and more people up. Hopefully we will evolve as a species to eventually cease the unnecessary conflict between different groups of ourselves.
