Conversation so far:
What conflicts did Marcus Garvey have with Du Bois?
Du Bois considered Garvey's program of complete separation a capitulation to white supremacy.
Can you elaborate?
a tacit admission that Blacks could never be equal to Whites.
How did he approach the situation?
Noting how popular the idea was with racist thinkers and politicians, Du Bois feared that Garvey threatened the gains made by his own movement.
Did they confront one another?
CANNOTANSWER.
Are there any other interesting aspects about this article?
Garvey recognized the influence of the Ku Klux Klan.
What was their influence?
Klan, the Anglo-Saxon clubs and White American societies, as far as the Negro is concerned, as better friends of the race than all other groups of hypocritical whites put together.
Why is that?
every white man is a Klansman as far as the Negro in competition with whites socially, economically and politically is concerned, and there is no use lying.

Question: Who else did he have conflict with?
Self-contained rewrite: Other than the Ku Klux Klan, who else did Garvey have conflict with?
