Sometimes I have thought they should just one time drop the cordon sanitaire and let Vlaams Belang have a go. Which would prove their shittiness once and for all, because like all European far right parties they are so much hot air, defined entirely by what they are against, and have no real plans for anything else (like properly governing a country). Of course, this requires them fucking a whole lot of shit up first, which is less than desirable.Sometimes, I think the best way to destroy the far right is to give them the oxygen of publicity and enough rope to hang themselves. And sometimes enough power to demonstrate that they're as unable to sort shit out as the mainstream.
The danger is when they get a bit too much power, and then rig the political system so it becomes very hard to remove them (e.g. Hungary).
Sigh, federal and regional elections next year. Not looking forward to that. Don't particularly like any of the choices we got right now.
