Dear Lavendar,
You ask
"But don't you think I should DO SOMETHING to help him see the deception of the WTS? By gently and lovingly asking strategic questions about the WTS, don't you think he will eventually realize he's been duped?"
Answer: YES!!! If you love your son, of course you will. Don't be confrontational. Use viewpoint questions. Be loving. Be kind. Be yourself.
The Oracle
PS: GOOD LUCK!
