Should we restrict freedom of speech?

If you don't agree with them it doesn't mean they are not illegal in many countries.

Just because it is illegal in many countries doesn't mean I can't disagree with the reasons for its illegality.

And you're right about perjury but it appears in a form of opinion, how one recalls the events of the past.

But it calls into question the very nature of the legal system and is nothing but lies - hence it isn't truly an opinion - it is just a falsehood.
