I have no expectation that any form of communication I make will be listened to. I can call my senator or Donald Trump on the phone but it's very unlikely I will actually be able to talk to them. I can send my senator or Donald Trump a letter but it's unlikely it will actually be read by them. There are many filters in place. Twitter blocks are just another filter on a specific communications medium.
Well, by that metaphor, Senators and the president should just ignore tweets they don’t like, same as mail and phone. That is different than returning mail to sender or blocking someone’s phone number.
