Yes, it's a mouthful. I actually combined two definitions. The long and short of it is that feminism doesn't take into account the many layers of discrimination that can impact women from different races, cultures, age groups, religions, abilities and so on. "Intersectionality" adds necessary nuance as we continue to unite for the advancement of women.
