I have read countless articles and posts at this point claiming that "America doesn't care about black bodies" and that black people in America should "fear for their lives every day," all in regards to the perceived danger of police shootings. In that example, despite this perception by not only those populations themselves, but a large majority of the population at large, the facts are that 1000 people (0.000003% of the population) are killed by police annually. 24% of those killed are black. No person has a statistically relevant chance of being killed by police, and yet it is not uncommon to hear it stated that this is simply this segment of the population's "lived reality." It isn't, and that's the problem.
I actually think that this is a central theme to many of these discussions, where one population is claiming that there is a substantial disadvantage to having a certain characteristic, whereas the counter states that there is either no such disadvantage, or its magnitude is misrepresented.
In any event, I think that there is often merit to both cases, and I think what you're seeing with the Facebook group here is simply a response to the growing perception that the conversation has become increasingly one-sided in the large SV corporations. Stating, as James Damore did, that the lack of female representation in tech is not appropriately attributable to workplace bias was a fireable offense. That's not okay.
