... ... I don't get it? The "look back" thing doesn't seem unreasonable, and neither does the "descended from 350 people" - there are other similar bottlenecks throughout history. Hell, 900,000 years ago, humanity's predecessors were reduced to roughly 1,280 people - a situation that lasted for over 100,000 years.
I admit that the "Criminals" comment isn't great, but (a) it doesn't seem related to the rest of the post, and (b) it doesn't seem particularly antisemitic. What am I missing?
