Quote: Nat Wicks @ November 23 2010, 2:58 PM GMTAnything presented as opinion is fine.
I think not, Nat.
Try writing on your blog, "In my opinion, John Jones, headmaster of Bash Street Primary School, Newcastle-upon-Tyne, is a paedophile" and see what happens.
I'm assuming Mr Jones and the primary school are real entities, of course.
Genuine opinions, not motivated by malice, and based upon established facts and well-reasoned arguments are safe if they are deemed 'fair comment' but whenever the words 'in my opinion' are preceded by or followed by an accusatory statement, you may find yourself facing an action for defamation.
And remember, you don't have to make a statement in order to be guilty of defamation: the most oblique suggestions of wrongdoing or dodginess can be defamatory too.
