The Devil's Dictionary (1881-1906):

SUFFRAGE, n.  Expression of opinion by means of a ballot.  The right
of suffrage (which is held to be both a privilege and a duty) means,
as commonly interpreted, the right to vote for the man of another
man's choice, and is highly prized.  Refusal to do so has the bad name
of "incivism."  The incivilian, however, cannot be properly arraigned
for his crime, for there is no legitimate accuser.  If the accuser is
himself guilty he has no standing in the court of opinion; if not, he
profits by the crime, for A's abstention from voting gives greater
weight to the vote of B.  By female suffrage is meant the right of a
woman to vote as some man tells her to.  It is based on female
responsibility, which is somewhat limited.  The woman most eager to
jump out of her petticoat to assert her rights is first to jump back
into it when threatened with a switching for misusing them.
