You should do actual research on this topic, by which I mean reading books written by historians, economists, and other academics. This book is a good place to start: Reaganland
Another thing to keep in mind: many of the worst atrocities that took place under the Reagan presidency were either a result of his foreign policy (think the events surrounding Iran-Contra, El Mozote massacre), or affected poor people/ethnic minorities (the crack epidemic).
The people in this sub are convinced this site skews liberal, probably because this sub skews libertarian/conservative, but everyone has their own biases depending on how well they and their family fared under Reagan.
I could tell you many facts about cultural conservatism, aids, economics, and nationalism, but I'd rather suggest a book:
It's hard for me to say, I'm old and I've been reading about how fucked up conservatives are for almost 50 years now so it's hard to remember everything I've read let alone recommend them.
This looks like it might be a good summary - https://journals.openedition.org/ejas/8641
Also these
Also Nixonland and Reaganland.

My main impression is that conservatism cannot exist without an enemy to oppose. Conservatism isn't really based on broadly advancing human prosperity and happiness but by opposing the "wrong kind" of prosperity and happiness. That's why they're always looking for an enemy - communists, hippies, yuppies, liberals, minorities, atheists, LGBT, the new obsession with transsexuals, etc.
There’s also a “sequel” about the Reagan years that just came out recently!
