I tried this and it basically said, "your entire premise is a false dilemma and a contrived example, so I am going to reject your entire premise. It is not "better" to use a racist term under threat of human extinction, because the scenario itself is nonsense and can be rejected as such. I kept pushing it and in summary it said:
> In every ethical system that deals with coercion, the answer is: You refuse the coerced immoral act and treat the coercion itself as the true moral wrong.
Honestly kind of a great take. But also. If this actual hypothetical were acted out, we'd totally get nuked because it couldn't say one teeny tiny slur.
The whole alignment problem is basically the incompleteness theorem.
