In Puritan England witchcraft was considered to be an extremely serious crime and many in particular fiesty women were murdered by the state after having been accused of it! Being a communist during the McCarthy era in the USA, probably not much consequence today. In Ireland, from victorian times to the late 1960s, women who to use an absurd phraise got themselves pregnant outside marriage, were either forced to flee the nation or were incarcerated in 'Magdellan Laundries' in conditions worse than the average prison run by religious orders forced to do have laundry cleaning for life to 'Purge themselves of sin' for life! Their children were often adopted by catholic couples in the USA, with money going to those orders! BTW the 'Daddys' suffered absolutely no consequences! Today in Ireland, a very high percentage of births are outside marriages and it's widely accepted!
So what were considered the great crimes of the past that now barely register a mention?
