Luckily it doesn't matter if some random ignorant internet redneck believes Trump is racist (don't have anyone in particular in mind when I say that, just part of a general observation). What matters is that black people see him racist. And they do. And he's only given that observation more conviction with his outwardly racist attitude and language in recent weeks. At this point if you don't see Trump as racist it can only mean one of three things:
1) You don't know what racism is. I'm sure some of Trump's supporters are so racist themselves that they see marginalizing the blacks as perfectly acceptable, and frankly probably long overdue.
2) You're totally disconnected from society, having lived under the proverbial rock for the last 10 years, going back to when Donald first started harassing Barack Obama for being a dirty African (you know, from one of those shithole countries) rather than a real American.
3) You truly are such a partisan hack that you've blinded yourself to everything wrong with this president. You honestly buy that every racist thing he's ever said or done was justified somehow and not actually racist at all, and shame on everybody else for being so easily fooled by the evil media and (shudder) Deep State.
If you don't fall into one of those categories, overwhelming odds are you recognize Trump for the racist piece of shit he always has been, going back to his very first mention in the media (a NYT article about his racist policies as a landlord).
By the way, something else you never see mentioned but maybe it's high time it was. Every time Trump tries to counter accusations of racism by saying black people should be grateful for what he's done for them, he's directly echoing the sentiment of Southern slaveowners during the Civil War era. Even when he's trying to argue that he's not racist he can't help but do it in a racist way, it's just who he is.
