I get your point. This whole string of issues is tied together, and is indicative of liberal thinking. It all started with Roe v. Wade.
I think it started before RvW. the environment was there before the USSC decision. I think it started before FDR - and that it started from within the dem party, yet is not confined there, for JFK wasn't exactly liberal in his policies nor ecopnomics - he is actually the father of supply-side economics, dubbed reagonomics by the press.
