Encouraging political correctness is stupid, and I maintain my case on that. However, you do make a good point with the rest of your post, and I am willing to explain that.
Trump needs to delete his Twitter. Seriously, he has shown incompetency solely through his Twitter and it's time to stop. Members of his party have encouraged it, nobody likes Trump's Twitter except the people who have their heads up his a$$. He also needs to grow thicker skin.
I will ask you this, however. If you were president, and everyone including the media was completely crapping on you 24/7, how would you feel? I'm not defending what Trump has said at all, but how would you feel on the inside?
He is currently the most powerful person in America. The 1st amendment exists for a reason, you can say as much bad stuff about him as you want. But at the end of the day, he is just as much the president as the first 44, I'm not sure what rioters are trying to achieve against him, he is president until 2020.
I bet you're a fun person to hang out with.
