1. Why do you think the Navy initially refused to identify Dorie Miller?

2. How do you think military service changed the lives of black Americans?

3. Why do you think white supremacists found black veterans so threatening?

The navy initially refused to identify Dorie Miller because several men were identified for that. So the navy refused as unnamed Negro Messman.

Explanation:

Dorie Miller was working as a Mess attendant. She will be having work in Messman. So she could not join the navy. Military service happened very strongly. It included all the powers required for black Americans. So it changed the lives of black Americans. Black veterans are wearing uniforms in public. So they are hating the fact of wearing uniforms in public. So white supremacists found them threatening.
