Can't you see the hypocrisy and uncharted narcissism in that statement?
You really are hopeless. Until you can understand your ideas of morality are not universal to all people you will never come to grips that your "live and let live" bs answer is based on YOUR morality nothing more.There was no rational behind sodomy laws so they were overturned. There is no rational behind denying two people of the same sex the right to a civil marriage. Whether or not it is a choice doesn't even come into play.
The arrogance is you pretending your morality is something everyone agrees with or that its the only "rational" point of view.
It would be funny if it wasn't so sad.
