Loving the Unlovable

The Bible tells us that we must love both our neighbor and our enemy. Because the two are very often the same person, it can sometimes get a bit sticky. If your neighbor, for instance, is someone whose political views you find not only wrong but repugnant, how exactly does that work? Are you really expected to love him? And if he persecutes you, are you seriously expected to turn the other cheek? Out of love no less? If a nation to be loved must first be lovely, as Edmund Burke warns, can it be any different in the case of unlovely people?
