Of course both are a problem. But I wouldn't say that white men going to a Thailand is a problem for the white UK community anymore than I'd say that the blokes doing this are a problem for the UK pakistani community. The blokes in question were held back by their culture and sexually frustrated as you suggest, they were living a western life style.
I'm not saying it is a problem for the Muslim community as a whole, nor am I suggesting that the actions of these offenders are guided by an Islamic belief (clearly it is not).
What I am saying is that there are specific factors, factors not evident in the wider British public, in Muslim/Pakistani communities that for me provides some explanation for the actions of these offenders. Specifically I have mentioned the discouragement of sex before marriage, arranged marriages and the fetishisation of virgins (linked to the discouragement of sex before marriage which effectively mainly applies to women). Don't get me wrong, I am well aware that no sex before marriage, arranged marriages and the fetishisation of virgins is evident in many many cultures but I'm specifically talking about communities in the UK, and in the UK it tends to be those from a Muslim background that have these traditions.
Now above you've criticised the Western lifestyle as being a factor, and far from labelling you a racist for suggesting that (as others have done for those suggesting factors associated with a Muslim upbringing have contributed to the actions of these offenders) I will actually agree with you. Western culture promotes sex. Sex sells and everywhere we are bombarded by sex, be it on TV or wherever. That must have an effect on us (probably the most obvious result is our high rate of teenage pregnancies). But you expose somebody from a culture that discourages sex into a society that promotes sex and to me you will have obvious problems that may manifest itself in the kind of offences that are the topic of this thread (those of us from backgrounds where sex is not discouraged only have our ugly faces as a barrier to finding an outlet for our sexual urges and alcohol is a pretty easy cure for that!)
Let's face it, sex offenders make up a tiny tiny proportion of any community/culture and in no way represent that culture as a whole. That goes for your white Thai peado-tourists, Catholic paedo-priests or these Muslim sex gangs that target vulnerable young girls.
What I'm trying to get at, if we forget anybody who IS trying to use this issue to bash ALL Muslims for a moment, is that the reasons and motivations behind why certain people commit sex offences will be different depending on that person. IMO, the sexual frustration built up in the sex offenders we are discussing in this thread has its roots in their upbringing where they were discouraged from having sex before marriage, there are certainly very few "up-for-it" girls from Muslim backgrounds and they don't even get to choose somebody they are sexually attracted to for a wife because that is arranged for them possibly before they are even born!
Now if people disagree with that then fine, but so far we have 42 pages (at the time of writing!) which has essentially been a discussion over whether or not we are allowed to criticise issues within the Muslim community of this country, rather than discussing this very real problem (no matter how widespread or not it may be). I think most of us will have had to skim through this thread at some point so apologies if I've missed it, but despite asking many times I don't think anybody has commented on the problems associated with arranged marriages (of which prompting some men to form sex gangs is the least of the problems associated with it, the main one being the rights of women, but that's a thread to itself)
So if anyone does care to comment on whether or not arranged marriages etc may have contributed to the actions of these men then I'm happy to hear you...
