The credible argument.... I'm going back to what David said originally about how you demonstrate knowledge of a language without being forced to speak it or communicate in it. I don't think there is another credible argument. How else would you do it? Is being forced to demonstrate knowledge of a language not a violation of the charter at that point? You're being forced to speak it. Doesn't everyone have the right to choose?
What's the argument? Can you walk me through the other credible argument on the other side?
