In "The Handmaid's Tale," Margaret Atwood explores the theme of division in society and the importance of unity among marginalized groups. The quote 'There has to be an us because now there is them' highlights the emergence of an 'us versus them' mentality that often arises in oppressive situations. This implies that solidarity and collective identity are essential for those facing oppression to combat the forces that divide and dehumanize them.

The notion of 'us' emphasizes the need for community and support, especially when confronted with systemic injustices. Atwood's work encourages readers to recognize the power of coming together, suggesting that the strength of unity can challenge the barriers established by authoritarian regimes. Ultimately, the quote serves as a call to action for individuals to foster connections and work collaboratively to resist oppression.
