Hi Desperately Afraid,
They will find solutions themselves...by experiencing the real life consequences of their actions. They will themselves see if their philosophies bear fruit or not.
Part of what 'happened' was we moved back to the US. He had never really lived in the US. He went to small private international schools.
We also lived in foreign countries. My son speaks multiple languages fluently beyond English.
The first time he bought a one-way ticket to Japan. (!!)
When he turned 18 he saved his Christmas job money to fly He flew to Rio to see a girl when he was 18 and ended up without money on the beach.
At the same time, he started to think his work was never good enough. An assignment for a 4-page short story became a maybe-publishable 12-page story.
This is not all bad. This is how academics and creative writers begin.
But frankly, we have been trying to get him to at least finish high school.
I enrolled my son in a private independent learning high school that counted all of his foreign experience, foreign languages, etc. as credits, and he thereby graduated.
he talks about revolution and anarchy, but refuses to examine the various historical instances of how such movements have succeeded or failed.
While I do not know your son, and cannot comment with authority, I might view these interests as vehicles to which to vicariously identify to separate and to emancipate.
I think these young people are so brilliant and their experiences have been so atypical they may have a hard time identifying with peers and their teachers may seem ho hum.
My son eventually was diagnosed with mental illness, hospitalized several times, applied for SSI for mental illness, and was qualified for such. I do not know what to think about this but I do not get a vote. My son's preoccupation with conspiracy theories scares me but I have learned to keep quiet. He is now waiting for the world to end (this month) and he realizes that it may not, and therefore needs a fall back plan. That is progress.
The best thing I did with my son was to allow him to explore and to experience the consequences of his choices. He realized he did not like being homeless. He did not like living near the street. He did not like being aimless and without meaningful and productive work. He was lucky to have found a community of immigrants from a country where we lived with whom he identifies. He is living with a family.
My son is now working doing landscape construction working for his friend and is thinking about returning to college.
He is still socially withdrawn. I am heartened because he is bored when he is alone in the house, and his friends are out and about.
You will learn many things on this site. It has worked for many of us to withdraw from micro-managing their lives and looking for solutions for them. That they will sabotage.
I am glad you found this board. Especially while your son is still young. You will be spared, I hope, a lot of the unnecessary pain.
