Final answer:
Feminists opposed Alice Paul's proposal of an ERA because they believed it would invalidate existing laws protecting women and end gender-specific privileges.
Step-by-step explanation:
Many feminists were opposed to Alice Paul's proposal of an Equal Rights Amendment (ERA) because they believed that the ERA would invalidate existing laws that provided certain protections for women. This included laws that limited the number of hours a woman could be required to work, the types of physical labor she could be compelled to perform, and welfare programs for mothers and widows.
There were concerns that the ERA would also end gender-specific privileges that women enjoyed, such as legal presumptions favoring women in matters like alimony after a divorce.
