The intent of the founders was that speech would not be censored. What we have today is censored speech through monopoly of control of the broadcasting systems in America.
If you are to reach the masses at all, it mostly must be done through some form of television. We can stand on a narrow interpretation of "freedom of the press" and we can be destroyed, or we can realize this is an entirely different ballgame than that with which the founders were familiar, and act accordingly.
I have further arguments, but if these don't reach you, I doubt the others will either.
This site alone represents the traditional freedom of speech of the soap box in the town common. The corporate machines that run the big papers and networks are not monopolies.
The mere fact that Trump goes directly to the people is proof that there is a free exchange of ideas. If twitter drops him, he will find another source.
That is how this is supposed to work.
