I'm always amazed how people talk about libel laws in this country, like they shouldn't exist.
The simple fact is that whether you're getting sued by McDonalds or a famous actress, being a lying cunt who lies about someone and damages their reputation or character deserves a bit of a pasting, metaphorically speaking. To wail that the law shouldn't exist and that you deserve some sympathy having lied about them is just absurd.
Which isn't to say that we don't need reform, and the most important thing is that justice is not deprived because of the threat of legal costs by richer parties, at which point it is not just, but a deliberate attempt to silence people by force. But that's the limit of it.
