Think about that for a second.
At no point did they think 'oh this situation looks shaky and we aren't sure how our precious ever so special 'daughter' will cope, perhaps we should look at something mixed sex which is less at risk from such problems for his own well being.
Nope they plonked him in Rainbows to get him into the system of affirmation and subsequent problems with reality which were fully foreseeable.
They literally sought out a scenario which they felt would be harmful and deliberately put their six year old child in there to prove a point and to demonstrate the self harm. They deliberate did the opposite of safeguarding to further their beliefs.
I hope this story isn't true, because the number of red flags is very alarming.
