Throughout history African Americans have always been at the bottom of the totem pole in society. Racism is still alive and well but now its systematic. Since slavery, we have been deemed "Angry n*ggers" or "Salty" because till this day it is still ingrained into our minds as a whole. Most of the time our job applications are turned down due to our names not being proper enough for their liking. Black women are degraded in society; our natural hair isn't worshipped it is overlooked. So are our bodies and full lips. Not to mention all of the hatred we've been given over time such as Jim crow, slavery, segregated schools and neighborhoods. And last but not least, white privilege. The list goes on and on but these are just SOME of the problematic issues in our culture today. Also, being swagger jacked by white women wearing bamboo earrings. White's using the word "N*gga" and non black people of color using it as well. Whatever we have, they take. I hope this answers your question and gives you a little insight!
