I don't think it is unneccessary titling, Buzzardbird, because of the racial profiles of the abusers and of the victims. It doesn't matter what racial/ethnic/religious groups the abusers and victims were from, as far as I am concerned - but what DOES matter is the possibility (or probability) that the abusers deliberately chose their victims from a different racial/ethnic/religious group.
It would be just as abhorrent if it were French men deliberately targeting American girls, or white men targeting muslim girls.
It looks as if there is a deliberate racial/ethnic bias to the way these men selected their victims, and going by what has been said in other cases (Rotherham etc), it seems as if men like these believe that white girls are easy/sluts/not worthy of respect - and are treating them radically differently to the way they would treat girls from their own community/racial/ethnic background.
If this is the case, this is something that needs to be dealt with firmly and fast. If there are men in one community/ethnic group that believe this about girls from another racial/ethnic group/community - then this attitude needs to be stamped out at once. To my mind this is far more important than worrying about whether the group should be referred to as Asians or whatever.
I don't believe that the vast majority of Muslims, or men from the Pakistani/North African/Asian communities believe that white girls are easy sluts and don't deserve to be respected the same way that girls from their own communities/groups do - but if that attitude exists in pockets within ANY community/group, then that community/group MUST take action.
