Good patches should not be rejected by the ground that anyone is anything. What matters is code quality.
ESR was talking about the issues the SJWs make wanting a code of conduct and other political things. That they should be kicked out of projects when they do that sort of thing.
If they submit good patches, it should be accepted. If they cause a political issue instead of a coding or debugging one then they are just stirring up trouble.
In the example the POC (People of Color) submitted several patches but only one or two got accepted because they were good enough. The SJW got upset over the fact that not all of them got accepted. Called the project leader a white straight male, and project leader replied back he was a Latino and accepted a few patches from POC and goes by quality not race to accept or reject a patch.
Really hard to tell a SJW from a troll pretending to be a SJW, Poe's law and all of that.
