As others have pointed out, this article seems poorly argued and makes very little sense.
Where is this poly community dominated by straight people? Where are these Poly Patriarchs the writer thinks are so common?
I did enjoy the line about people who claim the poly orientation but are in fact oriented to be assholes. That exactly describes my college boyfriend.
(In fact, because of the trauma I experienced with him, it took me years to recognize and embrace my desire for non-traditional relationships).
But I certainly don't think polyamory is any more of a haven for abusers than monogamy is.
