all of what ur saying is right in theory but in reality, colorism does exist. it's an element of self hate and a holdover from divide and rule. just because it isn't openly discussed doesn't mean it isn't an issue. the proof is in the pudding, whitening creams n papaya soap n shit wouldn't be a million/billion dollar industry were colorism not a reality. if all black people (n people of color at large) embraced and accepted ourselves/others of that race, it wld be a thing of the past. burying the topic from discussions n dismissing it as fake outrage won't change the realities of colorism.
when I was younger natural hair wasn't a topic of discussion. women didn't talk about being talked down to or conditioned to hate their hair in its natural state. fast forward to the present day n now I hear people in the workplace talking about going natural n discussing the moments their moms started relaxing their hair because it was "too nappy". ur colorism argument could be applied to black hair.
u r right that white people see us all as niggas ending in an r. however, there is plenty of evidence to show that there r still biases. did u not see the examples race jones dropped? there's a brilliant black psychologist at Stanford who is known for her work on colorism. I need to find her name again, but I recall reading that lighter skin leads to lighter prison sentences. still more likely to catch one than a white person, but not as likely to be punished to the extent of a dark skinned black person. so white people being complexion-blind isn't wholly the truth.
lets take a non-black example. India has huge colorism problems n a thriving bleaching industry. colonialism ended in the late 40s, they have a fast growing middle class n manufacturing industry, n they have at least a couple generations who never experienced white rule. n they're still dealing with self hate n complexion issues. do u think acting like it aint a reality undoes all that? cuz that is simplistic af.
