Very sad... I guess this kind of censorship / denialism is becoming an accepted practice in certain circles. I would have thought the moderators here are bigger than that.
p.s. I don't know about age, but only about 10% of HN users were in the Bay Area, last time I ran the numbers, and that was for a much larger region than most people refer to as the Bay Area (a 200-mile diameter circle IIRC). The SF number would be well below that.
