Do we really want some political committee sitting around and arguing the merits of these people's writing? What about weird kink websites? What about radical political blogs that advocate for policy you find dangerous? You may find some of these things abhorrent but there are almost certainly people who would find certain things you believe abhorrent.
Any time you get into individual selection of what is acceptable thought and what isn't you are crossing a very dangerous line. Even if the initial things that are deemed unacceptable seem reasonable.
Edit: Telco monopolies relating to infrastructure are essentially state actors. There is a big difference here between a Telco refusing to route traffic and a bookstore deciding what content to carry.
