The bit about the Indian Aid is a great snapshot.
So, there were (white) people working for the rights of Indians back then. And the article author doesn’t deny there have been wrongs committed by the “white” man.
Then it also refers to those who contribute as “liberal white men”.
Suggesting the authors & readers of this periodical may be something different?
Their objections here seem to be less that Indians don't need help and more that those claiming to help seldom actually do.
