Murdoch started out in Australia and one of his son's moved back there from America. He cut his teeth sowing social division and lowering social standards there, mostly in print, because TV and cable are more regulated there. Then he hit America and the gold mine with the GOP evolving into a fascistic party and front for domestic terrorism. He found this like his tabloid papers, made to appeal to simple minds with short attention spans and full of rightwing opinion.

The culture wars are largely their creation, there are others like them on hate radio, and like preachers, they share sermons, ideas and themes found to be useful and profitable.
