I don't blame gay couples for wanting to opt in to the same legal structures and of course they desire the same financial benefits. But that emphatically does not mean the definition should be changed.

Agreed.  The legal structures should be available to every adult.  That's why civil unions make sense.  Save marriage for the church if you must, but secular unions should be the default.

Please don't say "Agreed." when you disagree. You know perfectly well I was not advocating that the legal structures or financial benefits of marriage should be made available to gay couples, whether or not that is done under an "alias" (civil unions).
