It's a slap born of typical seppo ignorance, hence my suggestion for the poster to read "The Fatal Shore". The state of Georgia was founded as a penal colony (which they could no longer use after the revolution, hence the birth of transport to Australia). The fiscal and social success of Australia alone should be enough to show the wrongheadness of the "criminal strain" theory, but a quick glance at the crime rates in England pre and post transport would confirm it as well.
