Sorry to hear it.
I would suggest you get your son away from there as soon as possible.
You have just witnessed the first stages of the mind conditioning. They don't even know your son, but they do know that showering him with these lovely sayings, applause, etc. will certainly pull him in.
And insulting you this way before the whole congo is wrong!
I don't know how old your son is, but I'd put money on people starting to show interest in him now. Of course they'll have to point out just how bad "daddy" is.
Take care my friend,
Bryan
