I think there is a bit too much emphasis on "tone" being the problem. Trump is a loudmouthed brawler, but he didn't create the rather massive policy differences that so divide very large chunks of voters in this country. You could slap a bandaid of civility on the conversations, but the truth is that we'd still be just as far from compromise solutions.
@Maj. Bill Martin I think you are wrong - But not for the reason you state.
Yes I care somewhat about tone - Civility is important, and one can be firm in conviction without being boorish. But more to the point, he pisses people off just for the sake of pissing them off, with nothing to gain... And what that translates to is very extreme determination in his opponents.
And the proof of that is the white-hot anger against him, when really, he has not moved the status quo enough to worry about.
I will not say that will, like
@Jazzhead , but I will say that very well may cause a very determined left to roll out one helluva GOTV...
And that's just plain dumb.
