No-one said anything that could be remotely interpreted as "her whole argument is invalid".

I'm sure he'd be more than happy to discuss with Gebru where he agrees and where he differs on his Facebook page or at a conference panel. I think he explicitly said this.

He's just decided that Twitter is not the platform for that kind of reasoned debate. Gebru's attitude in this instance - providing nothing more than "I'm tired of this, you need to listen to marginalized communities" - was the straw that broke the camel's back.
