Why Hackers Must Eject the SJWs(2015)

How is a project leader on github even supposed to know their pull requests come from people of colour? I have no idea who most of the projects on github are maintained by or who is adding pull requests other than a user name. I don't think I've ever personally looked at a user profile on github, other than to look at code contributions, I dont even know if they have information about race and gender on them...
