do not believe that logic is sound and the argument is convincing.

To be honest, I may have some interest in 一夫多妻 culturally or even pensonally,
because it has been the family model in china for thousands of years. But I believe
that marriage only limited to two people is the best model for modern society.

Are 三人同性恋, 乱伦 good or beneficial for those invloved ? I hardly think so.
In rare cases, they could be still tolerated by a modern society, but to legalize them
is beyong the question.

hehe.
