(Playing devil's advocate here)
But perhaps the web has reached a point where we have to consider it as a public service. And as such should be subject to free speech laws. There is precedent for this with the "equal time rule" for broadcast networks regulated by the FCC which guarantees air time to opposing political candidates during an election. I could easily see an argument to be made for forcing service providers to dedicate a portion of there resources to dissenting opinion on these grounds. Although obviously the line must be drawn at hate speech, I shudder to imagine a world where acceptable content for the web is determined by the whim of an executive who "woke up in a mood".
