I seem to remember that the camp was supposed to be something like a one week gathering of members of the youth wing of the socialist party. They would be learning about political organising and activism. The youth are reported to be between 14 and 20-something. I don't see why one would be worried about it being some kind of "indoctrination". These are politically active youth. 14 would be on the young end of political activism, but not overtly strange to me. I had friends while in school who joined the youth wings of various parties in Sweden at 15-16, for example. And at the time they seemed to have a genuine interest in politics. Why would we be concerned that young people show an interest in politics and would attend political meetings? Teenagers are hardly some kind of innocent kids incapable of holding opinions of their own. Some of the attendees would already be of voting age, and also capable of standing for election. Others only a few years away.
