Gordon Copeland wants the Minister of Immigration to bar Australian euthanasia advocate Dr Philip Nitschke from entering New Zealand. He also wants the IT Minister to see of there is any way to "prohibit the establishment" of his website, Exit International.
Everyone has the right to freedom of expression, including the freedom to seek, receive, and impart information and opinions of any kind in any form.
While this is subject to "reasonable limits... as can be demonstrably justified in a free and democratic society", but I can't for the life of me see how a ban on people saying that people ought to be allowed to take their own lives, or even telling them how to do it could be considered anything of the sort. In a free society, people are free to advocate positions that others disagree with or find offensive or wrong. That's what "freedom of expression" means.
Bluntly, if Copeland doesn't like what Dr Nitschke is saying, then he has an obvious course of action available: argue against it. Show why it is wrong. Convince people. That's what you do in a free society - but rather than doing that, Copeland would rather use the law in an effort to silence his opponents. I guess he's just too frightened that they might actually win the argument...
