It seems the Netherlands has lost it's way since the days of the Pilgrims asylum there. My first subversive thoughts were to open up a real Southern Bar-B-Que joint selling pork spare ribs or a Church of Scientology across the street from the proposed mosque. Then I thought your dad should sue for false arrest and imprisonment for denying him his free speech rights.
Then I thought a more productive avenue for you and your Dad would be to become activists in the movement to prevent and vigorously prosecute honor killings.
