In this L.A. Times op-ed. "Marriage Can Be Expanded," the mathematician father of a lesbian daughter writes:
Each time the right to vote was extended, those who already had that right were indeed threatened. They could still vote, but their vote had less impact. But permitting two people of the same sex to form a union graced by the word "marriage" does not jeopardize those already married. It does not dilute the strength of an existing marriage...
If we were able to accept the ever-broadening meaning of the vote, which at each stage did threaten the existing order, we can surely absorb the extension of marriage, which will only strengthen the bonds that hold our society together.
An interesting analogy, which reflects how in free societies the
nature of rights is to expand.
