School Daze: Light Skinned vs. Dark Skinned

I was watching a film called, "Skinned" on TvOne last night which was written and produced by Lisa Raye McCoy.  It's very disturbing to me that in 2016, we still have a serious complex about image of Light Skinned vs. Dark Skinned.  As a child that grew up in Oakland, CA a very diverse place racially this is not something I ever struggled with or experienced this type of hate and discrimination.  The movie showed how a dark complexion girl who had Nigerian roots was always teased, ostracized and shunned away from as the "Ugly One" by her peers, her cousins and even her Aunt.  She was always treated like the black sheep of the family and was told constantly that no one would want her, love her, respect her or see her as beautiful.  The girl had such a complex that she ended up using bleaching cream which had side effects long term that made her sterile and unable to have kids as well as gave her skin cancer by the time she was 32 years old.  The young lady never researched the product before she started to use it & in the end she realized that it wasn't worth it.  This is very sad that we (as Blacks) still feed into this type of negativity within our own culture and are willing to tear someone else's self esteem completely down.  No one should ever have to be treated so horribly or unfairly especially at the expense of making oneself feel better.  Even within my own family we have an array of light brown, caramel, brown and dark brown women in my family we were all treated the same, treated fairly, shown love, respect and valued by all of our family.  I can't imagine being told or shown this type of hatred my whole life from as early as 4 years old all the way into my adulthood.  I would like to hear from my readers and followers have you ever experienced this or been a witness to someone else being treated in such a hostile manner?  If so, please share your story or experience in a comment.
