One lion was born an albino and is not accepted by the pride... Therefore, you can paint all the lions the same color, and then they will not perceive him as an outsider.

This only confirms what I'm saying. Why – see the answer to the next one.

I was asked the question "why does uniform increase pacifism?". Nothing more.

Stop. That's right. But – you claim that the difference in material well-being (which is expressed, among other things, in clothing) in some cases can lead to a child being bullied. Hence, aggression, hence the lack of pacifism. Is that right?) If not, then the uniform will not have any positive effect on pacifism.
In the case of lions, the albinoism of a lion is a problem in itself, and not its external manifestation. Painting the lions is one way to solve it, a rather crude one, but it solves the problem.

Of course, if a child is in a vacuum, they may develop complexes. But this is not a problem of the school uniform.

) I was saying that it is a problem of everything, of all factors, including the uniform. I may be wrong... But still, my own modest experience tells me that things are stored in the subconscious, which you may not even consciously notice. This is especially true in childhood. It is not a problem. Not some kind of horror that needs to be urgently solved and all that. But in the future, it may have an impact, and therefore it is better to take even such small things into account.

Regarding clones... well, you don't think that the uniform somehow limits the development, the child's imagination? And will the "clones" be stupider than those with free-form clothing?

It doesn't limit anything. But it can still have an impact. However, this is no longer relevant to the topic
