Reagan was arguably a neoliberal and Bush a neocon, but current Republicans have moved even further right straight to neofascism. The way that liberal democrats serve corporations over people proves to me that there is no longer a meaningful distinction between liberalism and neoliberalism.
It's hilarious that you think it isn't true. Other than hating gay and black people which isn't actually on an economic axis (necessarily...)
Reagan wasn't arguably a neoliberal. He was neoliberalism. The governmental policies of that era define the modern Democratic and what was the Republican Party.
It's not even entirely negative, deinstitutionalization wasn't done intelligently but there was rampant abuse in the system, for example.
