How about when the tables are turned and fathers lose their rights because they serve?? It's happened and it's not funny either way.
What about the children? Should they be taken out of school midyear and from where they have been living for sometimes more than a year. Keep in mind the children aren't living with strangers: we are talking about the other parent here. The interests of the children should come first, they are not property.
I have sympathy for every guy who was drafted who has had that happen in the last 10 years.
As to the volunteers, everyone has to choose between career and family.
