Final answer:
Butler's critique through Doro's dialogue likely pertains to Christianity, considering historical and feminist literature discussing religion and ethics. However, without explicit references to Butler's work, the specific religion critiqued cannot be confirmed with certainty.
Step-by-step explanation:
The religion Butler is critiquing through the dialogue of Doro is likely Christianity. This assessment is based on the historical and literary context surrounding the character Doro, as described in various texts that discuss the intersection of religion, rhetoric, and feminism. Doro's interactions and lack of moral judgement towards the poor can be seen as a critique of Christian ethics and charity. Moreover, texts such as An Angel in Ivory: Classicism and Christianity: A Conversation by Dr. Beth Harris and Dr. Steven Zucker and The Prophetic Faith by Martin Buber delve into discussions about Christianity's role in society, while Katie Cannon, Emilie Townes, and Angela Sims' Womanist Theological Ethics explore feminist perspectives on religious ethics. These references provide a foundation to understand the potential critical dialogue Butler is engaging in regarding Christianity through Doro's character. However, without direct reference to Judith Butler's 'Performative Acts and Gender Constitution,' it is difficult to definitively pinpoint the exact religion in her critique.
