phrenology is the basis of 'race'
Fact is that genetics are determined by isolated populations and distinctions based on skin color break down between races from differing isolated populations.
struggling with math and science
Genetically you are not like people in northern europe or wherever you think your ancestry comes from as opposed to people of different skin colors you are so sure you are different from.
There are learned behaviors that have a cultural basis but the only reality 'race' has
is from the learned behaviors of groups who identify themselves by skin color. I won't disagree that there are people of all manner of skin colors that think like you do but that doesn't make you better. If anything it just points out how alike you really are.
I personally expand my definition of racism to anyone who thinks we are fundamentally different by using skin color to categorize. I don't care if you think you are better or worse because of it.
