There are many other instances where you can't get away with something just because it is free speech. How come guys like Julian Assange are not protected under 'free speech'? How about people who sign NDA's? How come it would be heavily criticized (and probably illegal) for a newspaper to start running weekly cartoons where they make fun of the black population in America, depicting them with the all the token representations and slurs that are now widely accepted as 'racist'?
I really want to know what's different, what's permissible, what isn't. Are there some written rules about this or is it just the result of how things are perceived by the majority of the public (i.e. what we like vs what we don't)?
Disclaimer:
I'm not muslim, I don't sympathise with their religion and neither I'm trying to condone what happened. I made up an example with black people because that's a very sensitive and controversial issue in the US, but the intent is not to spark controversy around racism and the likes. I'm probably going to be downvoted into oblivion but I want to know if at least I get an intelligent point of view to these issues.
