Sorry, but something I’ve had to learn with time is that it really doesn’t matter who’s operating the gas chamber, if their actions rely on hundreds of other people openly saying “Death to all jews”. There’s no importance to whether those people would ever pull the lever themselves. The language is what’s important, not how much they were “only joking”. Both an ultra-racist and an edgy teen in their late 20s are just “trying to get away with it” and don’t care who they hurt.
