Dutch Elections and immigration

In Almere in Hoilland about 30% of residents are Muslim.
It appears that it is an enclave of Muslims and although they say they speak Dutch they still uphold their culture, which is fair enough, however, what isn't so good is that they are building their own social group and now threatening for unrest if Geert Wilders gets his votes and becomes the 4th largets party in Holland. This to me typifies the Muslim groups. If things don't go their way they start to threaten, but they say they are tolerant. It seems only if it's in their favour. What they are doing is proving Geert Wilders correct in his fears and it's likely to get worse. I can see a build up of resent from the Dutch and less tolerance. I spoke to a few older people in Holland when I lived there this year and they were not happy with the immigration policy in Holland. Although the older people are likely not to vote for Wilders, their siblings are.
I can see this spreading across Europe and is already gathering pace in Russia, Germany, Belgium, France.
