Bigoted?

If you follow Ms. Kersten's reasoning (from the BBC):

Police in the Belgian capital, Brussels, have arrested two far-right political leaders at a protest against the "Islamisation of Europe".

Police clashed with some of the 200 demonstrators and dozens more people were reported to have been arrested.

The mayor of Brussels had banned the protest, held on the sixth anniversary of the 9/11 attacks on the US.

...

The mayor of Brussels, Freddy Thielemans, banned the protest last month for fear it would cause problems with the city's immigrant population.

That last sentence is dressed up quite a bit. By "immigrant population" they mean "angry Muslims." (Which, knowing very little of the SIOE and their mission, seems to have have validated the entire point of the protest.)

What is going on here? Is Brussels' "immigrant population" telling the secular government of Belgium that it better perk up and listen because those who slander Islam need to be threatened? Is the secular government of Belgium responding by bartering away part of its free society to an unprovable faith equipped with dogma that seeks to deny anyone the right to resist it? Or is this group a bunch of xenophobe bigots?
