This is quite different from a lunch counter refusing service to neo-conservatives.
What society is trying to figure out is whether the Internet is like radio/TV broadcasting or publishing newspapers ... or something else entirely.
Personally, I see it as more of a community notice board, where anyone can put up any notice they like, subject to the whims of the owner of the board. Don't like the whims of the owner? Move along until you find a board that suits you.
I'm sure you're old enough to remember such message boards outside grocery stores, post offices & etc. and the differing rules each one operated under. Note that almost all of them had a disclaimer about the validity of messages, and reserved the right to remove any message that they deemed unfit for that board, in that location.
Note that freedom of the press belongs to he who owns one.
Note also that while you CAN get your personal message printed on the front page of the newspaper of your choice, you'll pay a pretty penny for the privilege. For a little less money you can place a classified ad. However, note that the publisher of the paper is free to nix your missive on purely arbitrary grounds (but usually because it would cost him more to handle the complaints than he would profit from the advert).
Also note that you can get your message broadcast on TV or radio, but again you'll pay through the nose for it. And it'll probably be prefaced and ended with a disclaimer ("The views expressed in the following/preceding message do not necessarily express the views of the Broadcaster, its advertisers, employees, or anyone else who has come within several million parsecs of the broadcast tower.", we've all heard it.). And again, if dealing with the bitching about it would outweigh the potential profit, the Company, having an obligation to the shareholder(s), might nix it.
But one thing I'm 100% certain of is that YOU are not allowed to use MY infrastructure to get your message out ... at least not without compensating me in any manor I see fit. I bought the gear, I pay for the electricity, I pay any license fees required, I pay the maintenance of and on the system, and for any consumables. It's mine, not yours. Period.
N.B. The final paragraph not withstanding, I would be quite happy to host Bob's personal web site gratis, if he had one and I was still in the business of serving web pages. Bob neither abuses the network, nor commits abuse on the network, and so would probably not noticeably affect my workload. HOWEVER, there is no way I'd turn him loose in my printshop, not without proof he knew how to operate a press ... Parts are scarce and expensive these days!
