What rhetorical technique is most prominent in the on right to suffrage poem?

The poem primarily employs parallelism as a prominent rhetorical technique to emphasize the parallel treatment of women and men regarding the right to suffrage.

Parallelism is characterized by the use of similar grammatical structures, syntax, or words in a series to create a strong sense of equality, comparison, or contrast. By repeating parallel phrases and ideas about men and women, the poem drives home the idea that if it is morally right for men to possess suffrage, then it is inherently right for women as well. This technique underscores the injustice of denying women voting rights solely based on their gender.
