What objections could you have against foreign language learning?

I copied this link from Ruxandra Comănaru who attended the conference “No island is an island” at the Language Show last week. The conference was organised by the EC and while it focused on the benefits of learning and speaking languages in the UK, there was one debate between Baroness Blackstone and Lid King that left all the attendants shocked, to say the least. She is a Labour life peer in the House of Lords.
