Imagine the consternation, wailing, and gnashing of teeth a sign like this would cause these days; geez just look at the hullabaloo over the moko'd guy that was refused entry of a Christchurch bar. Have New Zealanders become more pathetic over the years? – so sensitive that adults, at the first sign of hurt feelings, run off to tell on each other to the media, Fair Go or their mums?

What has happened, bit by bit over the years, is the corruption of what constitutes individual rights. At every turn there is seen a cultural shift towards a nation of grizzlers that demand a ‘right' to everything from everyone – there is no such right. This moko nothingness is all about the so-called right to not be offended, the so-called right to enter private property uninvited – regardless of the reasons. To make it easy for you, i.e. without having to go into a thesis on why no such rights exist, just think about the consequences of taking these rights to their natural conclusion – is that the country you want?
Now, no doubt you'll be saying, ‘...but banning people from places, or not giving someone a job because of an aversion to someone's race, age, religious persuasion, culture, gayness et al is wrong, and should be illegal'. While I agree that holding some of these phobias is irrational, that doesn't mean that holding these phobias should be illegal. Why not? – because phobias are ideas, not force; and therefore constitute nothing but a state of mind – how do you make that illegal while holding to the values of the right to free expression & free speech? You can't! While you may disapprove of someone else's ideas – regardless of how awful those ideas are – that someone has a right to be wrong; your only right is to persuade them of their error or stay the hell away from them – that's it, nothing else.
The property owner in question (while I think he's just the fall guy) is, as I said, quite rightly at liberty to decide who he serves in his bar, the moko'd one in question is quite at liberty to go somewhere else. Everyone keeps their real rights intact. If the Human Rights Commission penalise this bar owner, that is a breach of free speech and free expression – and that breach must be banned.
