That's because he is. He is expecting respect for the Constitution from a socialist radio network. He is expecting the staff of a "public radio" station to respect his financial support when the usual liberal mentality is to feel entitled to it. He is expecting respect for his unalienable right of free speech at the hands of NPR when his message is contrary to the staff agenda.
Liberals don't care a whit for such things and never have. The good doctor is irrationally projecting his sensibilities on a claque of fascists. He is probably a liberal RINO or "moderate" democrat who can't recognize the natrual progression of policies he has supported and is surprised when they are realized. He should know better and so should you.
