If you mean 'are these men abusing young girls for no other reason than that they are white' then the answer from the evidence in Oldham at least would be no. It's more likely that young white girls are involved simply because they are more 'available' than young Pakistani and Bangladeshi girls, more visible on the streets maybe? Have a read at reports of recent cases in Oldham, Burnley, Blackburn, Manchester etc, they all follow a very similar pattern of befriending, grooming and then eventually abusing their victims.
If you mean 'racial' in terms of a commonality in ethnic origin of the perpetrators then yes, there is.
I think a lot is down to how in the Muslim Community it isn't accepted for men to have casual sex, only in marriage. This isn't an issue for strict Muslims who are happy to follow their religion, but for 'bad' Muslims it is as unless say a bad Christian there's no normal route to casual sex. Thus they have to use these underhand methods.
As for why the victims are white, they could just as easily be black or Chinese, but the point is they have a strong concept of honour so don't want to dishonour their own Muslim girls. On the other hand they view 'kaffir' girls as already dishonourable. As to why they'd care when they don't follow the religion is there's a strong tribal identity involved in being a 'Muslim' even if you may drink alcohol and gang rape white girls.
