Two wrongs don't make  a right - you ever heard of that one? 

I had it beat into my head by my father by the time I was 8 and I think most anyone raised and educated in modern society knows it and knows the wisdom of it. Sadly something so simple and obvious seems so lost on those that didn't.

I can only guess you have heard the same argument you make made by so many others you have forgotten how asinine it is, or perhaps your upbringing has been so limited - regardless - you do not justify atrocities against anyone because someone else did it decades or generations earlier - that is simply feeble minded.

Fabricating atrocities like your Yugoslavia comment though takes an extra special kind of ignorance.
