Q. Please suggest resources on the basics/brief history of tenets of feminism

For the Basics of feminism: do a search on the word "feminism" in the Gale Virtual Reference Library. https://luthersem.idm.oclc.org/login?url=http://find.galegroup.com/gvrl/infomark.do?type=static&page=BasicSearch&prodId=GVRL&version=1.0&userGroupName=mnaluther&source=gale

Compare the entries to a website like bitch magazine:
http://bitchmagazine.org/article/everything-about-feminism-you-wanted-to-know-but-were-afraid-to-ask

and to the Stanford Encyclopedia of Philosophy site: http://plato.stanford.edu/entries/feminism-topics/
You'll find a range of definitions and a variety of viewpoints.
