A British Muslim extremist, perhaps a convert (judging from his name), has been banned from preaching on pain of arrest.

Incitement to murder is legitimately punished. This man's "vigilante patrols" may have included attacking passers-by. (Some such Islamist vigilantism in Britain has done that.) If he advocates Shari'a law, then he has no respect for others' human rights. He is evidently an example of the tendency for religions to inspire hatred, which is common today in Islam, Christianity, Judaism and Hinduism.

But that doesn't justify banning him from stating his views, which is not a crime. That tramples his human rights.

The UK fails to distinguish between "discrimination and persecution" and stating a political position.
