How the hell would this play into the hands of the Trump's of the world?
Let's use the NFL for an example. This stupidass kneeling business has been pissing off the fans since it started. NFL attendance is down, as is viewership and merchandise sales, and their own polls say this is a major factor. Trump did not cause the anger at the kneeling but he's taking advantage of it to fan that anger and win over people who are pissed off at what they see as an unpatriotic attack. Trump is a divider, but he mostly takes advantages of schisms which were created by others. This is something that divides people along racial lines and he's happy to take advantage of that.
In terms of the Sir John A statue and other such nonsense, it pisses of patriots. Progressives sneer at patriotism, but a lot of people feel it nonetheless, despite all people like Trudeau tell them about what a shitty, horrible people we have always been up until his noble glittering ass came on the scene.
