So who is the Master you serve?
Maybe a bad analogy?
If you have two children, which do you love more?
If you are remarried and have two different sets of children, which do you care about more?
Do you abandon your children of one marriage if you remarry and have more children?
Serving "Masters" is applicable if you consider yourself a "servant"
Do you feel and connection to the land of your ancestors.
Do you self-identify as a member of some ancestral ethnic group?
Reconcile the above in the context of dual-citizenship.
