He was more a pacifist. More like John Woolman than Karl Marx.
John Woolman (1722-1772). I remember reading of John Woolman the Quaker, many years ago. This was of his vision of heaven and his description of the horrors of exploitation in South America. This of the hapless indigenous people forced to labour in the mines.
Further to this I perused Wikipedia and read of his conversion to being kind to animals. All this a long way from the days of the anti-war activities. I trust that the healing might begin one day. I have seen too much tragedy in my life time.
