Yes, Trump's #NABJ appearance was an obscene display of outrageous racist slurs and fascist gaslighting. However, it went exactly how he wanted it to go. It was a win for him.
He didn't pull that racist "Kamala isn't really Black" lie out of thin air. It's a coordinated Republican talking point. Look at this tweet. He executed it the way he wanted, and then he got Harris Faulkner to pitch him softballs while his shills in the audience clapped.
