Final answer:
Sarah Grimke is recognized for considering the unique oppression faced by women of color, an understanding that aligns with the concept of intersectionality, which examines how different forms of discrimination, such as race and gender, intersect.
Step-by-step explanation:
In contrast to most early feminists, Sarah Grimke took into account the particular oppression of women of color. Grimke, alongside her sister Angelina, was notable for her activism in both the abolitionist and feminist movements. Drawing from personal experiences and the horrors of slavery they witnessed in their family's own farm, they made direct comparisons between the condition and subordination of women in the United States and the condition of slaves. As such, Sarah Grimke understood the interconnectedness of struggles against gender and racial oppression, an idea that resonates with the concept of intersectionality which highlights how various forms of discrimination intersect.
