I don't blame you for making these mistakes, as the information space is poisoned, but if you're interested in being correct rather than ideological you owe it to yourself to (at bare minimum) show me (and yourself) which Gaza hospital has been reduced to rubble.
In terms of "sappers" it is true that Israel has sent special forces into hospitals with confirmed Hamas presence, but that is very different from "bombing and leveling hospitals," an alluring but ultimately false claim.
This is all occurring against a backdrop in which Hamas has weaponized hospitals. For example, they brought Israeli hostages to Gaza hospitals. They have killed an Israeli hostage in a Gaza hospital (and sent video to the family of the slain hostage). They have built tunnels under hospitals. They shoot from hospitals. They meet in hospitals. etc.
