There have also been non Muslim prison gangs set up in UK jails (DBD) to fight back against the Muslims.
Set up by whom? One expects the authorities know, if you know, so what are they doing to prevent/avoid escalation, or is it being nodded through? Tell us more, because 'fight back' sounds like retaliation, which also implies the non-Muslim gangs are the good guys against the evil Muslims. I thought we were talking about prisons, where criminals are stored, so are the non-Muslim gangs made up of extremists or choir boys or something else? Without knowing the makeup of the non-Muslim gangs it's difficult to see where this is heading short of politically acceptable vigilantism.
I think you've been reading too much ENT.
