Last paragraph is kind of stupid because how are you going to know professor?
You can figure out that answer through self reflection and understanding yourself. Ask yourself why is lighter skin more attractive to you than darker skin. Think back about the comments you heard growing up from your family, friends, peer groups, etc regarding light skin and dark skin and see if it matches your current belief system when it comes to colorism. Be honest with yourself about how light skinned women are portrayed in the media vs dark skin women and how that affects how you view them.
Unless you give out some ways to differentiate you sounding just like the average online ranter on this issue IMO. Who really don't think they like what they like cause that's what they like instead of some white supremacy non sense?
It's funny because the comments you just dismissed wasn't even something that I came up with. If you read the works of Carter G. Woodson, Fredrick Douglas, and many of the prominent African American scholars and historians they bring up some of those same questions. They talk about how as part of our education in this country in the 17th and 18th century, we were taught that white was superior and black was inferior.
The fact that we're having the same conversation that our ancestors did predating the formation of this country let's me know at some level it's less about preference and more about conditioning. It's why to this day in certain Caribbean and African countries there's an epidemic of both men and women lightening their skin to become darker.
As I got older and I started to read more about where that shyt came from, I had to literally reeducate myself on how I viewed my skin color and why I believed what I believed about that subject.
