> Languages are tools, not an end in themselves

I suspect most people agree with this, and I don’t personally encounter a lot who or elitist or dicks about it. What is most common, in my experience is a complete lack of effort to (a) interpret what a incorrect phrase might have meant and (b) avoid idiomatic yet superfluous choice of words. These are a lot obvious yet contribute significantly to the inclusivity of a conversation with non native speakers. This, surprising, given how welcoming France is of foreigners otherwise.
