Sure, fear of crime was one of the mechanisms of white flight, but American fear of crime has a big racial component to it. Historically, America has kept black people poor, confined them to poor neighborhoods, and then blamed blackness for the high crime rates that go with poverty and desperation.
This game continues today. Donald Trump recently tweeted something with totally made up statistics blaming black people for murders of whites:

It wasn't just wrong and it wasn't just racist. It was literally neo-nazi propaganda.
This happens on the other side of the fence, and no one bats an eye about it. In fact, they call it democracy, or something like that.
Snarkiness aside, if these people agree with him, then that is their vote. Really, we can't have democracy if we don't call it democracy when people vote the way we don't like them to. It's the same as free-speech: we can't suddenly abandon it if we don't like what's being said.
There's also a particularly ugly history of populists stirring up racial hatred as a means to power, which I think is especially dangerous.
It's not that he's lying, because he doesn't even know what the truth is. I also think he doesn't know that he doesn't know that. In this regard, I think of him as like a sophisticated bot: he doesn't track input in terms of true or false facts, but in terms of word-strings to say that are useful for his particular purposes. Any belief necessary to sound convincing is generated from the word strings.
My grandfather was a master salesman and as best I can tell, this was his basic approach to managing reality.

If you narrative is American, race is an inescapable part of that. Saying your narrative has no race is basically to say that it's white. We white people can talk as if race doesn't exist because we have made whiteness the default, the perspective, the unmarked case. But non-white people in America don't talk like that.
If you're looking for an expanded version of how this works, search for critiques of "I don't see race", which has been thoroughly examined and found wanting.
If White Man's Burden motivates you to make the world better then so be it, but I find the idea incredibly divisive and at the height of hubris.
That's why, e.g., people on the autism spectrum recently came up with the term "neurotypical", so that they could try to create an equal footing in the discourse. In that construction, aspies and neurotypicals are just different kinds of people, both equally "normal".
Casting what I'm saying as "White Man's Burden" is either incredibly ignorant or a dick move, and I can't tell which. But to be clear, I'm up to the opposite.
The whole "White Man's Burden" [1] shtick rests upon the notion that white people are better, and therefore should help the benighted dark peoples. I, on the other hand, think races are fundamentally equal, and it's only an accident of history that leaves me with more privilege. I'm thus using it here to educate white people ignorant of the US's long history of ingrained racial prejudice.
Non-white people need no education on the topic. In the same way that nerds are forced to understand what nerdiness means to non-nerds, non-white people are forced to understand white notions of race, even as most white people see themselves as typical, average, default, "normal" and so never think about the topic in any depth.
Late to the party but I think Jews were also usually excluded.
