How odd. Here I'd gone all these years thinking that one of the rationales for not having government censorship was that ideas should battle it out in the intellectual marketplace. That bad ideas would be argued against, scorned, laughed at, and be left to wither and die on the vine. But now, apparently, when an idiotic idea is in danger of dying I have to water it, and nurse it, and help it survive?
Once again, I am pretty sure you are equivocating or misunderstanding the concept of "protect" as it applies to other people's speech. In another post you mentioned control of media and the news by larger interests. If someone is pushing a hateful idea that is propagating through the concerted efforts by just such forces, how would your stepping up to facilitate its spread be advancing the cause of free speech?
