From memory I think (please, someone correct me if I'm wrong) there were some articles about hiring on merit rather than promoting gender (and possibly race/culture) diversity as an ideal?
it's tragic that people think merit-based promotions and hiring actually exist. Meritocracy is flawed and extremely biased -- because people that enforce meritocracy are biased.
Martin himself shows himself to be a biased person which he shows time and time again on Twitter. What if he were to decide who got promoted or hired for companies?
Who isn't bias? That's what defines an individual personality. If we would remove everybody who expresses some biases you wouldn't have that much choice of people at the end.
The fact that people have bias cannot be the issue in itself, problems occur when they are ignored and not taken in account by systems.
For example a hiring process can take in account biases and have ways to correct for them, for example by avoiding to have one single interviewer having way more weight than another, by doing blind reviews, etc.
I object to using the notion of a "6X difference in murderer density" among Black men as a reason why police are justified in racial profiling.
But I also object to the extremely smug and faux-engineer-rationality of "This does not appear to be racism [...] It looks more like math."
If we're expecting Uncle Bob to be just some guy on Twitter I would write him off as a simple fool. If we're expecting Uncle Bob to be a thought leader in a consequential professional field requiring deep analysis and sound judgement, that's something else.
calling out the left in the US for promoting a cancel culture. And telling people not to remain silent or embarassed about having views other than the left.
