New Zealand First MP Ron Mark's suggestion in Parliament that National's Melissa Lee should "go back to Korea" rather than criticise something in New Zealand has been called racist, which it was, but it was also oppressive of free speech, which in Parliament is even worse.
Mr Mark is denying the right of immigrants to criticise their adopted country, which is an attitude heard often enough in general conversation where it is deeply oppressive for immigrants who are sensitive to the fact that they are recent arrivals and would like to join the conversation.
It is an attitude that should never be heard in Parliament, where it is essential to democracy that representatives of all shades of opinion, interest and ethnicity are allowed to speak.
On that basis, Mr Mark may say he should be free to express the view that immigrants who do not like something about New Zealand should go back where they came from rather than criticise this country. But Parliament has numerous rules that restrict its members' rights to speak in ways that abuse their rights or oppress the rights of others to be heard. This should be one of the them.
It is hard enough to encourage immigrants to stand for Parliament, as any political party can attest, for exactly the reason Mr Mark has stated. Naturally they wonder whether they have a right as new citizens to join in our political debates. We need to stress they most certainly do have a right. They have chosen to become citizens of this country, they are a large and growing minority contributing to its economy and we need to hear their views. It is not healthy for any country to suppress the voice of any section of its population.
