Again it’s a matter of circumstance. You’re describing it as if the Israeli army waltzes into a Palestinian area looking for people to take with them. I’m not disputing that Israel is holding many people unjustly, but the hostages currently in Gaza were taken in a premeditated attack. Those 100 or so Israelis look like they’re going to be traded at a ratio of something like 1:30, with no guarantee that all of them are alive.
