How does the following portion of Susan B. Anthony's speech support her
argument?
The preamble of the Federal Constitution says:
We, the people of the United States, in order to form a
more perfect union, establish justice, insure domestic
tranquility, provide for the common defense, promote the
general welfare, and secure the blessings of liberty to
ourselves and our posterity, do ordain and establish this
Constitution for the United States of America.
It was we, the people; not we, the white male citizens; nor
we, the male citizens; but we, the whole people, who
formed the Union. And we formed it, not to give the
blessings of liberty, but to secure them; not to the half of
ourselves and the half of our posterity, but to the whole
people women as well as men. And it is a downright
mockery to talk to women of their enjoyment of the
blessings of liberty while they are denied the use of the
only means of securing them provided by this democratic-
republican government the ballot.
-
A. It shows that most historical documents fail to address women's
rights.
B. It shows Anthony should not be allowed to vote.
C. It shows only male citizens are addressed in the U.S. Constitution.
OD. It proves that all citizens of the U.S. are given the same rights.

And we formed it, not to give the blessings of liberty, but to secure them; not to the half of ourselves and the half of our posterity, but to the whole people women as well as men.

It follows from the textual evidence above that the constitution was constructed by all and sundry and hence, proves that all citizens are given equal rights.
