Race Thinking Is Opposed to Class Based Thinking

Race thinking has a scientific backing to it, even though it's just pseudo science. It became associated with certain qualities that were indistinguishable from the person who was raced in that way. And so racism and the science used to justify it, is a very good justification for imperialism. In germany, after the prussian army's defeat by napoleon, the idea of race was erected to unite people against foreign domination. This was a pretence for nationalist wars.
