Even if you're right, which you're not, what is "Most" here? 51%? 63%? 90%?
Are you saying that it's bad if the majority of people are riled up to engage in violence following his tweet, but OK if 40% do? 10%? 1%?
Previous US presidents were careful with their words, as they know people will interpret them in different ways if they aren't crystal clear. Trump just does stream-of-through -> keyboard -> twitter, and we get to see the results. Which tends to leave lots of what he says open to interpretation based on the perspective of the reader.
