I have a feeling that far more people are offended by Trump's delivery of his message, than the content of it.
I'd even venture that he makes zero headway with the "liberal" end of the spectrum mostly because he has the social graces of a rhinoceros trapped in a hall of mirrors
I don't think I've seen it so elegantly put, that was rather spot on it's just I don't think people quite know how to put it as well as you did.
I've often have wondered where open dialogue has gone, my ninety five year old aunt hasn't talked to me since the election. We've always been able to sit and have open discussions on any range of subjects, I guess the old adage of "this too will pass" doesn't cut it these days. I think you bring up a interesting point that this is where social media and main stream media has taken us. It's all so critical and in the now because it's everywhere and everyone saying the same thing so it must be true, but like you said is it really true or is it really the likability factor that keeps people from expressing a different opinion.
I think a lot of problems with most discussions now days is because people don't take the time to express a opposing opinion in a well mannered structure way that doesn't insult or make the other person's opinion seem irreverent. I think it's very important to structure discussions in a fashion that leads more to a conclusion of, though maybe not stated in all cases, we will have to agree to disagree or disagree to agree which is more likely to prompt us all to come back on another day to see if we can find common ground on other matters.
