Such a loaded question for sure.
As a Christian, the easy answer is....Love your neighbour. It's pretty clear, even if we dont want to look at the old testament examples, that Jesus clearly stated we are to love everyone. Period.
But then you get into the geo-political spectrum and things get....Suspect. I don't have enough knowledge to be for or against the topic. But I do know....Ephesians 6:12.
So your fellow man, is never the enemy. That's what THE enemy wants. For us to hate each other.
