Good argument overall, but it shows signs of having been written in great haste. (Not to worry, the great Daniel Greenfield sometimes publishes pieces with a similar array of glitches.)
Your main problem is comma-splicing, this is when you start a sentence, and as it’s going well, you think of more things you want to say, so you tack them on, using a comma, to just keep things moving ... Tom the Son does this all the time if I don’t watch him.
Other than that, there are a few disjunctions where you left some words out.
On the content side, it’s my opinion that, to be fair, you should mention some of the occasions when Mr. Trump has encouraged his attendees to assault protestors at his rallies. You can say this is very different from the attack on him, because it is.
It was written in haste. Accurate. :)
