"This is objectionable to me, therefore, no one should be allowed to consume or be exposed to it."
That's what bothers this particular commentor (me).
My own access habits are in practice similar to one who is banned or suspended regularly.
I have never felt like I essentially have no voice on the internet.
I understand that if some popular person with lots of followers gets banned then it seems like they would risk losing a lot of their audience that they may rely on for income etc etc etc, but that's hardly the reality of the average 10/100/1000-followers user, is it?
Just because the big social networks are really big doesn't mean that they are the only places you can find a way to have a voice on the web. I don't mean to diminish your feelings if you feel that way. If you love twitter or fb or whatever and you get kicked out, then I certainly get that would be hard. But there are other places on the web. Lots of other places. Maybe some alternative places let you have even more of a voice precisely because they're smaller and it takes less to cut through the noise.
