Quite a lot of qualifiers there, wouldn't you say?
Is it your business if they are not happy?
Is it not a marriage if they are not healthy?
Actually if one is getting abused and one see's one getting abused it is one's duty to intervene. By intervening I mean to report the abuse (at least it is here). If I see you beating on your wife and I choose to ignore what I see, if something happens, yes I can be charged for not reporting the crime. When I say not happy or healthy I am talking about abuse!!
If someone is not happy just because then no that is not my business!
And what if we are speaking of three adults who are happy and healthy, etc.?
If they are adults and consenting, then they can do what they want. Still has no effect on my marriage. My marriage is between me, my husband and God...not the Jones or Smiths living down the street.
What if the relationship that they choose to claim is not "marriage" but parent and child? Should the state issue an adoption certificate and financial assistance to women with dependent children?
