What is that? America is already great because of the advances we made in the 1960s with integration, etc.
What the hell does that mean? Make America Great Again? Why did Reagan 1980 and Trump 2016 say that?
It means "Let's go back to the days when Jews kept to themselves, blacks were janitors, women never ventured beyond the kitchen, bedroom, and secretarial desk, Hispanics did nothing except mow lawns and pick oranges, gays stayed in the closet, the voting age was higher, and anyone who wasn't a middle-aged or elderly upper-class straight white Christian man knew that they were meant to be seen and not heard whenever they crossed paths with their betters." Whatever it may've meant when Trump first started using it, it's now basically coded language that bigots use to harken back to the "good old days." It's like how "America First" is a coded reference the fascist and highly anti-Semitic America First Committee of the early 40s.
