As an authorial technique starting off with a just so story about how marriage came to be that lasts several paragraphs and is obviously not at all how marriage came to be and doesn't even have the excuse of referencing some sort of supernatural source for being wrong might seem interesting but bored me too much to continue. I'm supposing the rest of it is also wrong and badly argued.
