Sorry silicon valley liberals, freedom of thought is too important to mess with

Nobody’s mentioning the 1st Amendment here. People are arguing principle, not law. You should let people speak their mind, no matter how offensive it is, or how much you disagree with what’s said, you still should be capable of listening and being able to criticise the content of the speech, not the speaker.

As a side note, it’s easy to argue that the xkcd comic is false, since banning a person from a public forum, effectively takes the person’s ability to speak. If somebody doesn’t want to listen, they don’t have to, but taking someone’s right to communicate their ideas is cowardly and uncivilised.
