“Should I be sad?”
I don’t know. That’s up to you I guess.
I think any kind of mass grave where innocent fathers and sons are shot and thrown in is sad no matter who they are.
The more you learn about this particular area of the world, the more you see that the various groups involved (Serbs, Croats, muslims) have taken their turns committing these crimes against each other.
An endless cycle of revenge for past deeds.
The ones who usually wind up paying are the innocent villagers trying to scrape by on their little farm.
Muslims in mass graves over Kosovo? Exaggerated hype to talk up bombing our fellow Christians in Serbia. Not kidding you. We supported terrorists from Albania over Serb Christians. Probably the most unrighteous war we ever fought. If anyone deserves reparations, its the Serbs.
