They are quite difficult for me, as a foreigner. I can imagine that this was impossible to pass (if they are real of course) for a person who wants to exercise their rights. It comes with a lot of stress induced by difficult to understand and catchy quieries.
I imagine that one can always create a language typical to some group and impossible to overcome by people outside of this group. I'm trying to learn music as a person who has never attended music school, and even though there is a lot of terminology in English available in the internet, the terminology in my country is different, uses different symbols and are inaccessible for me. My kids learn them, when I see it I cannot make anything of it, because of different coding of the same ideas (like intervals, minor major etc.) in the system that is imposed in my country
