This narcissism kept its place all throughout the centuries to this day. Ignore the customs and religions of others, and only focus on conversion. This mentality was taught to the Europeans - the ones who embraced Christianity the most before colonisation. CHRISTIANITY is what PROGRAMMED many Europeans to colonise in the first place. THIS IS VERY IMPORTANT MOST PEOPLE OVERLOOK THIS. People tend to just think that many Europeans colonised simply because Europeans are a wicked group of people. 

But first of all there were Europeans who DID NOT colonise, NOR force conversion to Christianity. Secondly, we see today that most Europeans who are pro-colonialist and racist are the CHRISTIAN ones, not the agnostic and atheist ones. 

And third, we see an increasing number of Europeans become irreligious throughout the decades, so much so that Estonia and Czechia for example are nearly nothing like they were 150 years ago. The churches are empty in those countries, they are simply relics of the past in Estonia. - So these reasons debunk that myth. The Europeans with large agnostic and atheist populations such as the Netherlands, Czechia, and Estonia (no not the UK, Sweden, France, Germany as even though those are popular countries those countries are about 2/3 Christian. So Christians still have the majority political and cultural power in these nations) the attitudes of the people concerning differences in human phenotypes is rather a chill one, free from narcissism and supiority feelings. Christianity teaches people to have feelings of superiority concerning their ethnicity OVER OTHERS - an extension of Jewish ideals of a chosen people and Us vs them mentality. With Agnosticism and atheism, the justifiability of us vs them based on ethnic grounds become increasingly difficult, to the point of futility - hence why most agnostics and atheists aren't racist because of a person's different phenotypes.
