He is a throw back to another era, an era I experienced as a kid but one some didn't experience at all.
Take a millenial, or an approx year of birth around that time. All they know is GWB and Obama. They would have been too young to appreciate anything about GWB except war in Iraq and they would have heard Obama apologize profusely and essentially tell Americans "we are all the same in this world and we have been bad to so many. Feel the guilt!".
Trump is bringing back Exceptionalism. He viewed himself as exceptional, and he likes others who drive themselves for similar goals. So, the younger generation is saying, "hey, we aren't a nice nation, we've heard this all of our life". Now Trump is telling them, "you can chase your dream, have a job, pursue your dreams. And you k now what? You do so in the greatest nation on earth".
It's a complete 180 and all the media who themselves are often not impressive people, intellectually or morally, now are having fits at his American Arrogance.
Yes, anti-Trump is anti-American, at least in theory. Nobody is above criticism in life, but, if you are going to tackle his agenda and policies you have to make one argument "are they good for U.S citizens or not?". When some say "free healthcare for illegal immigrants, Open Borders, we will increase your taxes and spend trillions on Green boondoggles that will hurt our economy and your opportunities". Well, clearly it's a very tough sell to Americans.
