My DD (16yo, Junior in HS) is in the middle of a weeks long project - ending with a historical paper for US History.  They have to ID an event of the late 20th century, research secondary and primary sources, come up with a thesis, and then write a paper defending their thesis.

After much discussion, she has come up with the following thesis:  That radical events and/or radical language that were used early in  the women's movement led to only incremental change; significant changes came when the women's movement used political (legislation and courts) to effect change.
