wikipedia aside, what happened at Srebenica was not propaganda. There are many books and articles that detail the massacre. Do your own search.
The truth is not based on the numbers. Otherwise we all should eat s**t as trillions of flies could not be wrong.
I formed my opinion DURING the battle for Srebenica and have observed how the false myth was created. You need to analyze the events, listen to the arguments from BOTH sides and carefully compare them.
