It's terrible when anything like this happens, really.
Although Fortuyn's ideas were generally ridiculous, no country should have to endure this sort of action.
I admire Fortuyn for wishing to preserve his ultra-liberal society, however his blatant, paranoid Islam-bashing, and the complete closing of The Netherlands' borders were not the way to go about that.
It's really hard to clasify him, but I would say he was certainly right wing, in a strange sort of way.
