Could people accept single family now?

Right now there have many single families especial in America. I think that if the family member will be happy with the single mother or dad, it will be accept in this social, won't it? However, I knew that some of family are still care about that their children get married with a person who is from single family. They couldn't accept that. However, the children who from single family. They always don't want to have a single mother or dad, but they don't have choice. It is cruel to them. Even though people know that divorce will hurt their children, they still do it. I hope the people get married before they could think that the future more serious.
