I want to know the answer to the following question:
What did Boas' argue against?
All the background I'm provided with is that "This has been particularly prominent in the United States, from Boas' arguments against 19th-century racial ideology, through Margaret Mead's advocacy for gender equality and sexual liberation, to current criticisms of post-colonial oppression and promotion of multiculturalism.". Is that enough to answer the question?
Answer: yes
