The problem with your point, it that Trump behaved like Trump always has. He's an aggressive, New Yorker jerk who is an alpha male and responds aggressively to attacks and is loud and obnoxious. Trump's behavior is what sets him aside from (and in my opinion above) the typical bland milquetoast politicians like Biden who are afraid to say anything substantive because it might offend someone.
And that would be fine if Trump knew what he was talking about.
For instance, he had to walk back his comments about the Proud Boys, pretending he never heard of them.
Seriously?
