It's called Freedom of Speech, not Freedom from criticism

You know what I love? When trolls make outrageous statements such as "Gay marriage will destroy the institution of marriage!" or "Women shouldn't be on the frontline because they can't open jam jars!" and when they get called on it, the first thing they do is accuse the person/people calling them out of infringing on the trolls right to freedom of speech.

This of course displays a pretty fundamental misunderstanding of what the right to freedom of speech actually entails. It doesn't actually mean that you can spout whatever crap you want and no one is allowed to call you a moron. Instead it pretty much ensures that if someone disagrees with you, they are perfectly entitled to use their own personal freedom of speech to ensure that you are made aware of their disagreement.

So the next time someone waves the old "right to speak" in your face during an argument, wave yours right back.
