The Marine Corps view the AV-8B as pivotal to their conops. So much so, that they feel that they need a STOVL version of JSF to replace it.
It is no more dangerous than any other tactical, single-engined, shipborne aircraft of its generation, and indeed landing accidents are rather less likely if you stop and then land, rather than trying to land and then stop.
And those who fly it have a more robust attitude to loss rates than armchair bound internet buffs, clearly.
