Doxxing someone for doing something that’ll make a lot of people angry is a dangerous game and should not be done unless you’re 100% sure you’d be ok with their blood being on your hands for exposing them to their would be attackers.
That said, poster rippers are mad about the right thing but at the wrong people. Those hostages are victims just as much as the people stuck in Gaza between the leviathans of Bibi and Hamas.
