> I think you should get used to the idea that reasonable people disagree strongly with the notion that they should be open-minded about any idea. There are plenty of things I am not open-minded about:
The examples you cite are obviously extreme, and so you obviously put me in a bit of an unfair position in having to defend them, so I will start out by unequivocally stating that I do not hold this belief, nor do I advocate it or believe it in any way.
With that out of the way, saying you would never countenance holocaust denial is in many ways equivalent to the Catholic church saying it would never countenance a heliocentric universe. The science up to that point was on their side. The 'known' facts and their religious scholarship were on their side. But they were wrong. Similarly, you know the holocaust happened because you've read it happened. You weren't there. You likely don't know anyone who was there, or if you do, their memories are quite old, and modern science knows quite a bit about how fickle memory can be. It is possible the the holocaust did not happen. Unlikely in the extreme, but possible.
Now, am I going to waste my time listening to a holocaust deniers argument? No, probably not. I put an extremely low prior on the holocaust being ahistorical. So low that it's unworthy of even the most passing consideration. However, that prior is not zero, and it should never be zero. If I started hearing enough people that I respect saying, "hey, you should really listen to this holocaust denier's argument, it's kind of interesting", I might start to pay attention.
My point in defending a non-zero prior for all beliefs is simply to illustrate that you have some prior belief about what this Google engineer has said. You either have or have not read what he actually wrote. I think it likely you haven't. Because what he actually says is fairly reasonable. Certainly not in the 'holocaust denial' realm of truth-probability.
If you have the time and inclination to post here about it, then you have the time and inclination to reject his arguments directly, rather than simply dismissing them out of hand. What is the point of that sort of dismissal? It convinces no one. It changes no opinions. It adds nothing to the universe. This guy made a rational, intelligent argument in support of his case. He cited studies, he explicitly embraced the ideals of diversity, but simply disagreed with a few of the methods. If you disagree, that's fine. But have the courage to do so substantively. Maybe you'll change some people's minds, and actually further the cause you seem to be arguing for.
