There's plenty of rhetorical devices used in this pieces which can be ripped to pieces.
First, who defines bizarre, bizarre is defined culturally, morally and also individually.
What's bizarre for you, may be perfectly normal for a Rastafarian living in Jamaica.
Awhile back, women voting, owning property or working would have been seen as
bizarre...
Couldn't the poor little wives be happy being supported by their husband, who
obviously knows what's good for them...
Secondly, the definition of marriage itself does match well with the religious definition because
civil law adopted that definition which was pervasive in a Judeo Christian society.
In many society it started more a contractual obligation with much cultural overtones (less
influenced by relgion than by the role of men and women in the culture in general). The
fact that it was a man and a women was incidental, only relevant because of the reproductive
aspect. The marriage was mostly an exchange or money and status.
The main reason for gays wanting marriage is that there is so much legal case law
and jurisprudence about countless contractual documents with employers, governments and service
providers, that getting the ability to marry enables to not have to fight
all these legal battles all over again.
If they were able to create something with identical legal rights
to marriage (but not the same name) in all those
documents called "yapyap" instead of marriage

, I'm sure most would be satisfied with
that.
I'd love to get YAPYAPPED...
