I'm not sure that the way you worded it is really any different. Stating that there were good, well-meaning people in a crowd of hateful rascists after a woman was killed by a radical maniac is not a helpful statement, and it provides cover for what was, by most decent people's assessment, a despicable display of bigotry and hatred.

I also do think that commentators are WAY too quick to impart meaning to Trump's words in situations like this. After observing his actions and statements for 4 years, I'm quite confident that he doesn't think much while he speaks. Words just dribble out in stupid ways "stand back and stand by" comes to mind. Trump never learned to speak or think with any discipline. So it's like he follows a Markov chain of words -- I can't say the phrase you've asked me to say ("stand down") because that makes me look weak. However, "back" and "by" follow the word "stand" with high degrees of frequency, so let's just go from "stand" to "back", and then for extra measure (because saying lots of words makes me look smarter), let's try another phrase - "stand by". No real thought of the meaning behind that.

And that's one of the biggest points about this individual. Not only does he have a complete lack of empathy and a complete fixation on himself, he doesn't communicate with enough precision to provide real leadership. No wonder qanon has so much fun searching for hidden meaning in his words; it's effectively just word soup, which can lead to all kinds of interesting crazy conclusions.
