Do you feel that open Polyamory is a threat to something?
It probably is. It does not follow that such a something is worth keeping, however.
Do you feel it should be "hidden" from the children?
Not really. I've grown quite weary of the insistence of some people in taking pains to keep children unaware of how things actually work in real life.
Is it something you feel will somehow hurt society?
To an extent. But again, hypocrisy hurts society far worse, so it is probably worth it.
Will it destroy the family unit?
For some definitions of family and unity, it well might. Again, I don't see how that it would be a bad thing, either. Some understandings of "family unit" come straight from hell.
Will it give some "kinds" of families an unfair economic advantage?
I beg your pardon? I didn't know that families were ever meant to avoid unfair economic advantages. How would that work?
Putting aside ALL RELIGIOUS issues...
What is it exactly, that governments and people are afraid of regarding Polyamory?
Seems to me that it is mainly that they would jeopardize many traditional, albeit fairly meaningless, references for social roles.
Many people are pretty much enslaved to a tradition of choosing such roles with no regard for actual vocations and feelings. Polyamory is a direct threat for those silly, hollow traditions.
I just don't get it.
Blessed be.
