I don't see how you can avoid the fact that the books are riddled with sadism, racism, sexism. In books, readers tend to skate over all these horrible ambiguities. The moment they're put on film, it's very difficult to duck them.

Ageism is as odious as racism and sexism.

"Isms" are tools used by those who wish to control the weak for their own selfish pursuits.

Excellence is the best deterrent to racism or sexism.

Advertising and marketing philosophies that thrive on emphasizing 'natural' differences don't stay in the realm of advertising and marketing--they spill into how we justify sexism and racism at every life stage.

There is oppression that shouldn't exist. There is a struggle for freedom all the time. There are very serious dangers: the species may be heading toward extinction. I can't see how anybody can fail to have an interest in trying to help people become more engaged in thinking about these problems and doing something about them.
