Some points made here are:

1. The National Socialists were "Virulent Racists".

2. The NSDAP used "Niche Marketing" to gain African support.

3. Africans were propaganda and campaigning tools for the NSDAP to gain votes.

4. The Nazi Germany "exploited" the racial tensions in the US in order to get African-American troops to "desert".

5. They "demonized" African-American troops serving the American army.

6. Nazi Germany "whitewashed Afro-Germans" with freedom of church.

7. African-Americans were promised "false comfort" by the Third Reich.

Are there any rebuttals that could he used against these claims?
