You participate and feel that you belong to a society in the same way you would do for a family. The members have to be your own. This has been empirically shown to be true in every single case. If I force my way in your house and you are legally obligated to consider me part of your family, you might for a while, but your level of participation and your willingness for it will drop by a lot. Pretending it isn't so will not help anyone, it will make things harder. Japan, to their credit, does not pretend.
