Well, I remember seeing Somali trolls using racist terms in Twitter spaces, where there are discussion between different groups of African descent. Well, apparently some AAs didn't like being called with those racial slurs and promised they would take action.
You can dismiss it all you want, but social media how people communicate nowadays. And what we say online when we attack others for no reason has repercussions. I have yet to see Eritreans, Ethiopians, Kenyans, or Tanzanians in the hot seat. So what is wrong with us that we act disrespectful to other people and choose to deploy the most disrespectful language against others?
