Facebook bans far right group but not halal group

In a completely expected move Facebook banned a far right group in the UK on the grounds of inciting racism. This comes after Facebook refused to act when the head of the Australian halal association posted on Facebook telling Australian men to kill themselves. To date Facebook has failed to act against the muslim bigots. Is Facebook policy fair? Is it equal? Why did Facebook kick out the UK far right group but not the halal group inciting people to end their life?
