Is this sort of action really productive? It may have some symbolic importance, but does it really make everyday Swedes in this town happy they are there? Did they provide a service? Fulfill a need? Fill a power vacuum? Or, did they just inadvertently cause some immigrants and delusional leftists to get violent?
The BNP and other serious nationalist parties in Europe rarely lead marches through the streets. It's not really an effective tool. That time marching and waving signs - while costing the city money through the overtime they have to pay police - also could be better spent picking up trash, repairing buildings, delivering food and clothing or even passing out literature.
