Ms Parman relayed what, to her, was the meaning of "Make America Great Again."  I think it's likely that each of us has our own interpretation of the meaning of that slogan.  She sees it as an expression implying racism, others see it as implying elitism.  Others, I'm sure, see it as ending what they consider the dominance of liberal thinking.  It would make a very interesting exchange to get together and each share our personal view of the slogan.  It's ambiguous or, if intended, it's equivocal.  However, in my opinion, there's no "right" or "wrong" interpretation of the phrase.  It would also be interesting for someone to "pin down" Mr. Trump by having him explain just what he means by his use of it.  

Communications are often analyzed in terms of their "intended meaning", their "delivered meaning" and their "received" or interpreted meanings.  I think this one would yield some very different opinions.
