I hope you've heard of bell hooks. She is a USian black woman, a Buddhist, an artist, an acclaimed feminist theorist, cultural critic, and writer. Her work is focused around understanding the ways in which systems of exploitation and oppression intersect, and ending them through education and relationship.
In my opinion, the best way to get to know bell hooks is through her writing. She has written for 40 years on the interplay of racism and sexism in daily life. Highlights of her work, for me, include Feminism is for Everybody, We Real Cool: Black Men and Masculinity, Teaching to Transgress: Education As The Practice Of Freedom, and All About Love, but every single one of her works is worth reading, with care and attention.
You can also see her in action by looking up "bell hooks" on Youtube. There are many videos of her giving lectures, seminars and interviews.
