Yes I've met some.
I also know that they were the ones who killed Pym Fortuyn (the real one)
"Animal Rights activist"- worst Euphimism of the 21st Century.
Pim, not Pym. Dutch for "Bill".
Volkert van der Graaf was not a muslim. He lived in towns where hardly any muslims live (Wageningen, Harderwijk). He was born in Zeeland province, hardly any muslim lives there. Although he said he killed Fortuyn because he considered him dangerous for his anti immigration policies, it is more probable he killed him for his policies on animal rights, and more specifically on Fortuyn's ideas about keeping animals for their fur.
