You left out something interesting, and it's definitely a thing: the two parties have practically switched sides on key positions.
Reagan-era conservatives:
* Were in favor of illegal immigration (or, "undocumented" in common parlance). It kept businesses profitable, and they didn't care if it hurt American workers without college degrees.
* Opposed free speech. Reagan appointed Edwin Meese (an evangelical) to be his Attorney General. In 1984, Meese released a scathing report detailing the harmful effects of pornography.
* Thought America's might was largely a factor of its military dominance and the strong influence of large corporations.
All three of these positions are now identified with the democratic party, with some degree of variation and for slightly different reasons, to be fair.
