This was only ever true in online discussion forums, Usenet, etc. I agree that there is a lot of mob mentality going on, it’s just difficult to get upset about this case because the original author was spouting debunked “biotruth” arguments. Twitter replies are mostly full of men who didn’t read the original memo or who are willfully pretending it didn’t claim women are less biologically suited to being engineers. I like Pichai’s memo and I think it sets the right tone: the offending employee could have raised these same arguments without falling back to debunked stereotypes. He could have done an hour of Googling on the topic and educated himself. Instead he trusted his own feelings in an area he had no experience or knowledge in. This seems to be a trait relatively common among really smart people: doctors who think they’re good at politics, mechanical engineers who think they’ve discovered a theory that overturns all of physics, or in this case a software engineer that thinks he knows better than thousands of scientists doing experiments and crunching the actual data. As far as I can tell we can have rational critical discussions in tech - we just can’t get away with spouting nonsense. If that nonsense reinforces old sexist or racist stereotypes then we can expect a backlash.
