Academic system failure:
It's not important that #Cofnas is a racist. It's important that he is a shit philosopher, who doesn't (want to) understand human behavioural genetics. He twists and cherry-picks his evidence to support racist dogma.
He won't be fired because his views are indeed vile. He'll be fired because his methods fail to adhere to basic standards of research.
If you keep on supporting him, you endorse the ensloppification of academia. This has nothing to do with free speech.
