Comparing cultural traits in these politically correct times can elicit rebukes, but brushing over the differences can be even more costly.

With more than a million migrants welcomed into Germany and thousands of others into neighbouring countries, Europeans are asking hard questions about cultural differences. Can Germany integrate so many migrants without having to change its cultural norms, such as what is considered acceptable dress for women? Did culture play a role in the sexual assaults on New Year's Eve celebrations in Cologne? The migration crisis has forced Europeans to debate these pressing questions but many wonder whether it is too little, too late for Europe.

In Australia discussing differences of culture and religion is often frowned upon. The popular response is to present an image of compassion and universalism, but this misplaced projection of common humanity reflects a dangerous mix of arrogance and ignorance.

There is a presumption that all cultures resemble our culture, with the same hopes, aspirations, norms and rules. The arrogance of this view emerges through the idea that our values are universal. This argument, commonly held by the left, sees Western European history and its roots in Christianity as inconsequential. Instead, the human rights movement that went global in the 20th century is somehow regarded as common to all peoples and nations.
