i don't even think you need to get beyond the good old harm principle. can speech harm people? sure - and when it can, we should push back. but, the bar needs to be set extremely high. speech is almost always harmless.

like most things, i'm more likely to lean towards chomsky than foucault on speech, but i'm not as absolutist as he is. i think we're using the same framework, i'm just more likely to recognize the potential for harm.

but, the basic point is expressed here: you have to be reasonable about what you're trying to shut down, or you're just being a terrible hypocrite.

if you can tell me who you think that a novelist is harming in exploring the viewpoints of different people, i'd like to hear your argument. i'm not likely to take it very seriously, though.
