but narcissists can't deal with anything foreign
If you mean me, I did deal with everything foreign more and better than you or anyone you know. Name one person who one sunny day left everybody behind, got on a train, and just left the country with no one waiting at the other end. No destination address, no job, and no money. You can't so why don't you drop the narcissist crap.
languages have their own logic,
Logic and Polish language should never be used in the same sentence. There is a reason why English is everywhere and Polish nowhere. Even here, it's a me-too language.
