Final answer:
Phyllis Schlafly was the conservative detractor who believed that the Equal Rights Amendment threatened traditional gender roles, arguing it would undermine family structures and special protections for women.
Step-by-step explanation:
The conservative detractor who felt that the Equal Rights Amendment (ERA) threatened traditional gender roles and values was Phyllis Schlafly. As a conservative attorney and activist, Schlafly spearheaded the opposition against the ERA, asserting that the amendment would erode family dynamics and special protections for women. She was particularly worried about the implications for homemakers, the potential for women to be drafted, and the loss of preferential treatment for mothers in child custody battles. Schlafly also expressed concern that the ERA would pave the way for government-funded abortions and promote the LGBTQ agenda.
