I think people are missing the issue here, his friend was raped so he went looking for any black person.
The issue here isn’t the rage it’s that he went looking for any black person. If his friend had said a white person had done it what we he had done?
If we heard a Muslim or a black person say “I was hoping for any white bastard to attack me so I could kill them” would we be patting them on the back for being brave?
