I'm a grad student in the humanities so I have a vested interest but I would say that your comment may apply to some humanities but it is also the humanities that is where people are exploring the negatives of cultural domination and the value of diversity.

I'm in media studies and use cultural studies, gender studies, and anthropology (which likes to claim it is a "science" but I don't really consider it one). Those fields along with things like post-colonial studies are all about examining and tearing down the systems of cultural domination.

As someone who got my BA in English, I find it difficult to understand why some humanities departments are as large as they are at large research universities. Literacy and literature are very important but I don't know that we should be churning out very many people with phds in English.
