St George's parade racists, Islamic Sharia law isnt

Here is something for you to consider.
A BBC news article here tells how a St George's Day parade in West Bromwich has had its funding withdrawn and been cancelled after being funded for the past 5 years.
The story mentions that:-
Council leader Bill Thomas said: "[Their] evidence showed categorically that extremists infiltrated the parade."

Now compare this to a story in the Daily Star here about a march in London today calling for Britain to adopt Islamic Sharia law.

Now, correct me if I am wrong, but surely this march is guaranteed to attract and involve extremists, but is not banned or prevented.
