Hitler's nationalism agenda had racist elements which is not present in Trump's "Patriotic Education." Hitler only cared about the blond Aryan super-race Germans, not other Germans such as German Jews. Not all nationalism results in Nazi Germany. There are some very diverse countries with sizeable racial and religious minorities, such as Singapore, but they are very proud and nationalistic. They also have "patriotic education" such as singing the national anthem before class everyday.
Trump and conservatives are not racists, and believe that all people have equal opportunity (through merit, hard work, etc.).
Trump and conservatives believe that all people are born with the same intelligence and can overcome humble backgrounds through hard work. I do believe this is true; it is very easy in the U.S. to go from poverty to solid middle class and even upper middle class in the same generation or one generation without the help of benefits.
The Democrats' view of equal opportunity is racist because they believe certain people need extra help because they are incapable (as seen through Biden's racist remarks); many African-Americans have remained poor for generations despite voting for Democrats and living in Democratic-held cities.
Democrats have done a successful job at painting conservatives as racists but this view will only last so long; I'm glad the Trump administration is reaching out to minorities.
Trump's patriotic education basically consists of showing some respect for the founding fathers and "American heros." Of course bad aspects of our history should be covered but they should not be the primary aspect of U.S history, which is what the Left has done.
