I am also a proud ECU grad and I think you sound like a whiny child. You are in for a difficult life if getting blocked on Twitter by someone causes anxiety. He has no responsibility to carry on, what clearly was intended to be a one way conversation with you. He has no responsibility to allow you access to his Twitter account. Blocking you is not silencing you. You are still free to yell from the roof tops your views.
Good luck in life. You will need it…there are no “safe spaces” in the grown up world.
