They don’t have an answer, because deep down they know there is no defense for these “schools” (they don’t deserve that term TBH, they were flat out concentration camps), but they don’t want to admit any of that because they, or their ancestors, or their organization, were either part of running it or benefited from it. It’s the exact same story with all those Catholic clergymen trying to defend them.

It’s just a desperate, pathetic attempt to save face, avoid the responsibility of making restitution/reconciliation to the people they harmed, and to gaslight the public and/or their supporters/followers.
