Well, maybe and maybe not. Is anyone, including the Donald himself, sure what the guy "really" means?
But this got me thinking about another word in wide common usage in several eras whose meaning has changed pretty radically during my lifetime. Interestingly I think the expression is now on its way out of any usage.
When I was an aspiring Berkeley radical and hippie in the 1960s, certain that we could not trust anyone over 30, the world was divided into two camps. There was our tribe of the young and enlightened -- and outside our circle, in hopeless social conformity and ignorance, there were the "straights." Straight people just didn't get it that a new world was aborning. They demanded that boys cut their hair, girls forgo sex, and all of us should finish school and get a damn job! "Straight" meant conventional and boring but usually too out of it to be threatening.
Twenty years later, "straight" had acquired a different meaning -- it had come to refer to heterosexuals, especially ones who were hostile to our LGBT "lifestyle." These straights might get gays fired, toss us out of apartments, reject people with AIDS, bar us from church, or beat us up. Some straight people were just uniformed and could come around to know us, but some were dangerous. To call someone "straight" implied a need to be wary.
As LGBT people's presence in society has become widely considered "normal," even when not fully accepted, the latter usage of "straight" seems to have gone away. I don't miss that.
I do miss the former usage of "straight" -- it wasn't always hostile. Sometimes it just meant people who didn't understand ... Thinking about this, I wondered what I might call such people now and was at a loss. That is, I was at a loss until I remembered that J.K. Rowling of Harry Potter fame had given us a contemporary alternative: folks who just don't see the magic are "Muggles." Now there's a useful category.
