but the one thing I really can’t get around is auto-uniformization aka dressing a particular way, not because a job or other cirumstaces require it, but as symbol of personality or faith. Its one of humanities quirks that I just don’t grasp. I can’t get around peoples insistance to be different, but only in a big group doing the same.

I think that is one of the things where humans just differ. There are people that value belonging to a certain group very highly, and also like to communicate that. I don't think there is anything wrong with that. I wouldn't object to people wearing lets say football shirts of their favourit team. I wouldn't do that but it doesn't really concern me. People are allowed to build their personality around whatever they want, as long as they don't actively annoy people.

I wouldn't say wearing clothing is actively annoying anyone. Clothing for me is (at most, some/most clothing just has no to little meaning) a kind of passive communication. But I do understand that that is my opinion and that others have an opposing opinion on that.

Where I would draw the line with clothing and messages is when the messages are about other people. Wearing clothing showing you are a strict christian? Fine. Wearing a shirt that says: death to all non-vegans? Not fine. Even though I personally like vegans way more than christians.

I think where a lot of this conflict stems from is that in the western world we associate uniforms or just clothing with an explicit message with mostly bad things. My mind jumps straight to military, bikers, or other violent groups. In my opinion it's important to acknowledge that this is different for other cultures.

That is a bit unconstructieve, and a bit childish.

That's true, but it's also a very human thing to do. I wouldn't fault them for being a bit rebellious if they are staying inside the rules.

Like I said if you enter into a scholl system it is proper behaviour to abide by the rules.

Totally. But the rules should apply to everyone equaly. If there are no muslim signs, not even gestures like that dress allowed, then no crosses, no fishes, nothing christian should be tolerated either.

But in a school setting I would say that that is not a place for religious signalling. [...] Like when I get to visit a religious building I will respect their rules, even if it’s not my own religion.

I think that those two things are not comparable though. A religious building is dedicated to one specific religion. I would consider it offensive to go there uninvited and showing your disbelief in this religion.

A school is a public place where you are allowed to show who you are in many ways. You can wear merch of your favourite band, you can show what sports you like and dislike, you can even communicate your sexual preferences if you so choose (as long as it stays SFW). But for some reason just showing which beliefs you carry is a very hot topic. If I understand correctly part of it is getting the influence of the church out of the french schools, which I support. The church should have no influence in the teachings in public schools. But I wouldn't mind people showing that they are catholic, with the same restrictions as every other topic. Don't actively annoy me with it.
