Ignorance is rampant and as a Brit i'm extremely used to that on American forums. You read the headline and nothing else and that's good enough for you to base your opinions on.
Sharia courts settle civil matters as long as both parties agree, it cannot bypass UK law in any way shape or form. Think of it as a lawyers office, they can come to agreement or they can take it up in legal court, that is all that it is.
This group isn't banned, it's banned from protesting because of the rioting that ensues every single time. This is equal to yelling fire in a crowded theatre and has nothing to do with freedom nor rights.
Our biggest problem in the UK is and remains to be the Indians who follow the honor system, that is where you find fathers who burn their daughters with oil or throw them off balconies because they don't marry who they are supposed to, that is where you'll find men murdering their wives rather than granting them divorce, that is where you'll find men burning women with acid because they had the gall to turn them down.
99% if not more of all honor killings or abuses in the UK are Indians trying to follow an archaic rule of caste in the UK.
Of course, they just do it to their own so you don't hear much about it in the worldwide press.
Yup, few people give a shit as long as they are just killing their own people.
