This is an awful idea! Not only is it dictatorial and probably unconstitunional, it sets a precedent for the future. You might not like twitter, but who`s gonna be next? And if Trump can do this so can future presidents who might not be conservative.
Afraid you've got that backwards - the social media platforms have set the precedent. The question is now what to do about it. Nothing is going to come out of Congress, so that's out, the companies are not going to police themselves since they are in collaboration with domestic and foreign political operatives, so that just leaves one man to stand in the gap between us and them. Worrying about what may or may not be in the future is a waste of brain time since the communistas have made it quite plain what they will do no matter what any law or a regulation says. Support the President, while we still have one.
