for now you have political movements like Shariah4Belgium
Shariah4Belgium disbanded in 2012, as the page states. Millatu Ibrahim have 50 members apparently - and it seems like they've done fuck all. The characters in Four Lions achieved more.
Were the two who lobbied for the dog ban successful? If they were, I'd be worried. Otherwise, chalk them down as two loud idiots.
I'm bullet pointing my responses as per the linked articles from here:
For the general statistics portion you gave, the vast majority of the links aren't working - they just send me to Google Translate. I won't comment on those headlines alone, they're often very misleading.
The sex offender article (the sixth link in your general stats bit) also says "the police say the phenomenon is not restricted to any one race – the vast majority of those on the sex offenders register in Greater Manchester are white (95%). You're taking a quote (from a muslim, who's part of an organisation aimed to ease tensions, notably) thrown in at the very end of the article.
...I'll edit in responses to the remaining bits later! Sorry, I need to go and do stuff other than argue with people on Reddit. Cheers for the response though, a lot of good material to work through!
