I do have these doubts too from time to time.. but I always have hope into the possibility that these forces can be somehow "dispersed" into other passions.. football, other sports, song contests, whatever.. there was a research here some time ago, stating that people who got really worked up about some team sport or other contests (watching, not necessarily participating) were much less inclined to engage into extremist political views, be they right or left. Obviously there are exceptions, as a lot of hooligans are also often inclined towards the far right, but in general I have found it to be true, as long as these contests are not about a NATIONAL thing but a team one or even a single star or feature.
Bread and Games, always the old thing....
