Each person and each group should and do have the right to form their own system of interactions, whether that is religious, political (or lack of) or anything else, providing they do it at will.
When a child gets brainwashed by their parents, it is against their will.
Indeed, one's own thinking system is one's own right too. Brainwashing is essentially the imposing (injecting) one's thinking inside another's without his will. (Like when you're put by force to memorize a book and then repeat it.) Or the prohibiting one from thinking his own thoughts.
The fact is that a person has always tried to make a cat and dependent on himself, therefore in society It always happens. Everyone in the family has someone in the bathroom and imposes their ideas and thoughts, And children always go to subordinates. It has always been such a person's nature and I think that excitement in this plan can not be any.
