The whole situation in Uganda is tribal, NOT Christian. The tribal whackjob who is in power has decided he's Christian now, but he's crazy and his whole viewpoint is based upon TRIBAL tradition, not Christian tradition.
Is this a bad time to remind her that Christianity was once a tribal religion?
Christian tradition has largely changed, but people fought in the name of God the Father not
that long ago. And what we know as 'extremist' Christianity was alive and well through much of Europe until fairly recent times. Stop acting as though it was something done in medieval times. It's just history. It shows your religion is a powerful one. Is that a bad thing?
