The emphasis on 'intent' is the second problem. Genocide cannot be committed by recklessness, negligence or good intentions that lead to the road to hell. In most legal systems, this tipping point about intention makes fundamental differences in both criminal and civil law. When the Turkish minister for the Interior instructed his armed forces to 'destroy completely' and 'terminate the existence' of the Armenians who lived in Turkey, there was no mistaking what he wanted done. Similarly, when Hitler had killing centres established to complement his concentration camps - where inmates were murdered directly upon arrival rather than being worked to death - there was no ambiguity in his objectives. These genocidal regimes were aware of history.
The world's first concentration camps, whereby people were held because of their ethnicity and died in their thousands due to the malicious, reckless or negligent methods of the local commanders was well established. Such camps first opened in Tasmania in 1824. Further camps followed around the turn of the 20th century, with the conflicts in Cuba, South Africa and South West Africa. The difference was the scale of the deaths due to incarceration now ran into the tens or hundreds of thousands.
The above two problems link into the difficulty that many instances of colonial policy do not fit the criteria for condemnation, as often the targets of colonial policies were the culture - not the bodies - of the people. In addition, the question of intent was often far from clear. This was the pattern in New Zealand. Outright racial discrimination against Maori was not enshrined in the law, unlike the Chinese who were the targets of racist legislation.
Nevertheless, Maori were the target of legislation which had the effect of disrupting, damaging or destroying large parts of their culture and which almost led to the loss of their language, traditional healers and parts of traditional family structure. It is debatable if any of these acts were done with an overall evil intent. In contrast are those laws which facilitated the outright theft of the resources that were guaranteed protection under the Treaty of Waitangi. The foremost example of this was the Settlements Act of 1863, through which more than 1,200,000 hectares of land were confiscated from Maori tribes.
Subsequent actions at both the national and local levels often continued this trend of taking land, whilst other resources, such as the foreshore, have been kept from the hands of the original owners.
Although some of these resources have been returned over subsequent generations, especially post the advent of the Waitangi Tribunal, the lasting social and economic impacts that that these confiscations had on many Maori cannot be underestimated. Similarly, the damage to the integrity to the other partners to the Treaty, for failing to honour what they committed to defend, cannot be understated.
If these acts and crimes were not a holocaust or a genocide, the question is whether they amount to a cultural genocide?
The answer is they do not as the term genocide is a tightly reasoned legal term, designed for specific crimes. Aside from the difficulty of trying to apply standards to earlier times when no such standards existed, once the prefix of 'cultural' is applied, the idea becomes meaningless.
The history of humanity is about the evolution of different cultural systems. Unravelling questions of intent, complicity and bias over hundreds, if not thousands of years of history is very difficult.
It is certainly wider than condemning 'African' slavery and 'colonial histories'. Slavery was wrong when committed by any culture, as were (and are) crimes against humanity - no matter who committed them. What is different to the past is that many countries have now evolved to the point where the rule of law, equality, freedom and democracy actually mean something. The Third Reich was never going to support a multicultural society, apologise for its past mistakes and compensate the people who it stole from and intentionally liquidated in the Holocaust.
