Nothing is worse for a nation state than a state of lawlessness, so the law should be enforced. Legal systems are not naturally given. If systems are unjust, oppressive, they should be changed. People may think that in certain situations the law is unjust, that the imposition of the law is producing lawlessness. So, this question should be answered entirely in context, in the context of transition in South Africa, but at least it is a legitimate law, agreed upon by all, so it could be enforced.
Language is dislocated from the territorial, the national.
This is why we see nationalist responses to it. So there is a threat to local idioms, to languages and so on. Up to now we've thought the political is linked to a territory, but now we see that power is not linked to a territory, a nation. It's a general dislocation which is threatening, but we can't stop it. One has to interpret the process and orient it.
