Donuel: What you don't have is Constitutionally guaranteed free speech.

You're quite right. We don't have 'Constitutionally guaranteed free speech' in part because we don't have, or need, a 'constitution'.

In Europe, or the EU if you prefer, the situation is that something is illegal unless it is specifically permitted.
In UK anything is permitted unless it is specifically banned.

I hope that you can understand this basic difference, and understand how it applies to American law.
