I really don't see anything wrong with marrying androids. Robot is a slave, so I don't see much of a point in marrying one of those... but if an android is a person, why deny them the capacity? A marriage is, after all, an agreement between two persons.
Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
