It's a topic that runs afoul of several major human biases -- and the biases involved in this topic happen to be exactly some of those that, statistically speaking, happen to sneak exceptionally well under the radars of the sort of people who hang out here, and who are otherwise usually so attentive to eliminating bias from discussion. Therefore, you need lots of tact and a very good didactic approach to avoid ticking people off when talking about it. I think pjeby did an amazing job in that regard.
