"We perpetuate systemic crimes against humanity but the real crime is in calling that out."

One of things I have found is that the hubris of imperialism and colonialism means they openly admit their crimes and write it down in their newspapers, books and webpages, and in this day and age video themselves doing the crime. I first discovered this for myself when I was younger reading about British Imperialism against India; they were essentially boasting back to the base that they shouldn't let go of India in the Scramble for Africa.
