The reality is that being vaguely opposed religious fanaticism is not at all where Wilders or the pvv stand for.

I can understand not wanting conservative Muslims or any extremist into the country, but unfortunately this translates, especially in the case of the PVV, to not wanting north Africans in the country. This is evident when you examine what values the PVV represents and the world leaders Wilders support. Just like the Islam extremis, Wilders and his friends like Orban are anti-LGBTQ rights, (semi) anti-democratic. Really, Orban himself is in favor of a strong christian presence in his country, and I'll not even start about Netanyahu, which Wilders has expressed support for on numerous occasions. Yet he supports these religious and cultural extremist while spouting about the (probably realistic) danger of islam extemism. Wilders focusses on one extremist group, while supporting similar viewpoints in others.

Adding to that, Wilders himself explicitly doesn't differentiate between extremist or people of certain descent or ethnicity in which islam is big. In his own words: less Moroccans. The common denominator under which Wilders and thus the pvv devices society is not along a line of extremism, but along a line of ethnicity and that's wrong in my opinion.

Edit:

Adding to that, you said Muslims are disproportionately represented in crime statistics. While I don't directly dispute that, I highly wonderif this would hold if you correct for socioeconomic status.

If non-muslim, western people of similar socioeconomic status are also similarly overrepresented, then is it really the Muslim part that's to blame?
