I don't see or hear any "children" in this video. These are adults who are unwilling to grow up, in particular the guy who acts as a leader, moderating the meeting and obviously enjoying to act out his resentments towards his parents (or proxy adults).

I've just read this first paragraph and will read and answer to the rest later.

Mayber exactly this is the projection?
Is the 'leader' hurting anyone?
Coercing anyone ?

But you need to defend your parents who probably did that, cuz he offends them ?

defending the abuse to not to let the child express itself and to suppress it because of parental problems

it is only a child, does not know many things and has to learn them - stupid adults do not understand and take it personally

I see no grown ups, only projecting humans who are stuck as children because of the trauma they do not want to work off. Mostly out of fear. Fear to offend anyone.
and this results because they were treated like that themselves and were suppressed, not allowed to express themselves and punished
so they teach that their own children, not allowing them to express themselves cuz they could offend someone (especially the parents)

Then one can also just take the hanging route again and say before 'I sacrifice myself cuz if I wasnt, I could offend someone"

okay, read the next one:

Parents treat their children like children because they are their parents. Only when you can prove to your parents, by means of your later adult life, that you can take responsibility for yourself and your life, will they begin to take you seriously. As long as you complain to them about their mistakes, about their evil deeds towards you, you are signaling to them that you are still a child. So they treat you like one.

So you can only fix this by seeing ur poor adults are also only traumatized children.
And you need to care for them now? and ofc already as kid - yeah the children care for the parents
cuz it is how it is

Great job as a child.
Best recipe for complete traumatization and NOT BREAKING this generational traumatization chain

children are already complete one does not need to erziehen/ drag them to something - to 'educate'
just need to let them entwickeln/ entfalten/ unfold - become what they are
instead of traumatizing them because the parent also wasnt allowed to unfold and develop

Only when you can prove to your parents, by means of your later adult life

so you have no fucking chance as children, because you are defined as children and need to wait until you are a adult and have enough fear to then also not offend your parents
maybe you need to go out and tell them how you really feel //// offend your parents finally to prove that you are not a child anymore?

but then one cannot drink 'relaxed coffee' together and play/ act as if everything was okay :/// :((
xD

watch the video from 8min 25sec and listen carefully

people suppress their own bodily feelings (needing to puke) just cuz they are trained from kids to NEVER OFFEND ANYONE
xd
perfect recipe to sacrifice and to never get to know your own self
