I don't see anything wrong with having tolerance, free speech, respect for others, respect for the place where you live as values. They are not exclusively British and something that everyone who lives here can take ownership of and subscribe to.
All the kids at DS school know that we should behave nicely and take ownership of the values above because they know that it makes the school a nicer place for everyone to learn in.
As for learning the language of where you live, it just makes it easier. It means you can go to any shop and ask for what you want if you can't see it. You can ask for a bus ticket, ask what the time is if your watch has stopped, where the toilets are, watch all the channels on TV not just a few. I'm brushing up my Spanish again so I can ask for things when we go there this summer, makes things easier, even DS will be learning some.
As woodenspoon says above there is the one of democracy as not all countries are democratic, but it is one that one can take ownership of without necessarily having experience of. It is also one that countries other than our own do have too.
