Practical and on point because Trump talks about things that the common American actually gives a shit about in a way that the common American can understand and relate to. This also has a side effect of uniting people under a common cause despite outward appearances.
Gruff because that style of speech appeals to most Americans who don't like being sophisticated, or worse: Being politically correct. Remember that being politically incorrect was one of the reasons Trump won in 2016, and it's still one of the reasons he won again today.
Charismatic because, well, I think everyone has to at least admit that the man draws people in despite any and all odds.
If the common cause is being against other people, that's still divisive.
His practical message was incoherent; it was more of an erring of grievances, conspiracy theories, and wild policy ideas that he seemed to have come up with while speaking.
I can't argue with the fact that it appealed to people, but you can't say it wasn't divisive because it was practical and gruff. Those two things don't rule out divisiveness.
BTW, I voted Republican in every election until Trump, and the reason why I didn't vote for him was due to how divisive he was.
I think you just happen to agree with his side of the divide.
I don't know whether this was deliberate or a typo, but it's funny and apt.
