The following three lines indicate that all human beings are equal in the poet's eyes:

I am the poet of the woman the same as the man (poet of both)

And I say there is nothing greater than the mother of men.

It is clear the use of comparisons of equality in the previous sentences from the poem of Walt Whitman.
