Thanks for this comment. I'd like to acknowledge that as you point out the 6.6% figure refers to exits from Gaza via Egypt using documented means, and may include people who exited multiple times, so the actual people exiting would be slightly lower. Similarly, it'd be nice for you to acknowledge that this figure doesn't include undocumented exits via tunnels in Rafah, or the 424,000 documented exits from Gaza via Israel.
In those conditions, it's hard to pinpoint an exact figure, but whatever the precise figure is--5%, 6.6%, 10%--it's clearly higher than zero, which is what one would expect in an "open air prison," the central point I was arguing against.
Aside from the exit rate, the "open air prison" claim is a lie for many other reasons, not least of which is that the guards patrolling the so-called prison (Hamas) are also the people who were claimed to be inmates, something one doesn't see in prisons.
The claim for Israeli persecution is not false (or "trivially false" as you put it). The odds of a gazan dying from an israeli weapon in 2022 was essentially zero: hamas claims 49 were killed that year, of which 22 are verifiable. The odds of a gazan dying from Hamas on the other hand was appreciable, in the thousands. After hamas's genocidal massacre on october 7, obviously this changed.
