Well, if you read the link dahfisheroo provided, the “drawbacks” listed are of much, much graver possible consequence than anything that might happen rollerskating. The site lists: losing family, your kids, your job, your friends, your mates, etc. This lifestyle is not protected by the law in any way that I can see. It is not outside of the realm of possibility that it could explode into a thousand pieces, MUCH to the detriment of the children.
A possible scenario which involves “on-the-side” relationships: One of the spouses decides that he or she doesn’t like the poly lifestyle anymore. He or she sues for divorce, and the kids are put in foster care due to a perception that the household and/or the parents are unstable or unsuitable by a judge.
Another possible scenario involving “living as a family unit” relationships: There is a poly family (let’s say, a married couple and another woman), the woman is very attached to the children, and they to her, even though they are biologically the married couples’. The couple decides that they are not interested in maintaining the relationship with her, and kick her out. She was not married and is not the legal parent of the children, and therefore has not a legal leg to stand on in terms of ever seeing the kids again. She & the kids are devastated, but have no choice in the matter. Likewise, she could just choose to move on, and the couple have no recourse, because there is no legal tie, and again the children are devastated by the loss.
Of course, if a parent is a responsible one, they will be cautious not to let these situations happen. But I hardly think it’s just like roller skating…just another way for a parent to have some fun…and not something that has to be taken very, very seriously and cautiously.
One other way it is not like roller skating is that when a parent goes out to have other love relationships, it is not just taking up time, it is taking up emotional energy. I don’t know how much other people have in comparison to me, but sometimes I have trouble keeping up the drive to give myself just to my family, never mind maintaining other relationships as well. Friends will usually forgive you for neglecting them when these tough times come…but will a lover? And what happens then, when they are demanding time & attention? If the relationship is at all important to a person, I would not be surprised if they would work to maintain it, even at the expense of their family.
So, sure, like any activity, it doesn’t matter if it never affects the children. But the possibility that it might, and in such devastating ways, makes me think that it might be a desire that should be put aside when there are children involved.
