I think they are partially constructed due to the statement 'we are bound to those we hate'. The enemy provides cohesion for the social group under stress. Because it is representations of the self that are being projected, there must be recognized kinship at an unconscious level. The familiar enemy remains feared - but familiar - strangers. Thus those groups from which we most passionately distinguish ourselves are those groups from which we most separably bound. We end where they begin.

The identity-creating process results in the world being divided among groups with varying degrees of animosity, escessive self-regard, and fear of others. We need enemies to keep our treasured - and idealized - selves intact. Enemies, therefore are to be cherished, cultivated and preserved; if we lose them. our self-definition is endangered and our cherished group is threatened. Hence the reason why Turks and Greeks passionately dislike each other like the Trojan War has never ended.
