25,000 Muslims March in England to call for laws to Silence Critics of Islam.

you have repeatedly stated that those who protested should "move", implying that they should not have the right to express themselves.

I think you're reading it wrong.
The people who are protesting have all the right to do so.
Just, considering where they are living, they shouldn't expect that protest to have any effect.
The UK is not in the habit of making that kind of laws... not for their own CoE, nor for any other religion.
Given that it shouldn't have any effect, if they really do wish to live in a place that has the kind of laws they protested in favor of, then they should move to such a place.

Ever since I was a kid, I heard the old saying: "quem está mal, muda-se" == Who isn't well where he is, moves.

So, when you were a kid, you were taught by your ignorant parents (I presume) that if you don't like government policies, you should leave your own country and go elsewhere rather than protest and stand up for your values and ideals? What you are basically preaching is that you either should like whatever the govt does or get the hell out. Do you understand what's wrong with this opinion and why the people who taught you that are ignorant?
