You've been taken in by the Serbian version of holocaust denial. You can also probably still find endless web hits deriding the notion that Milosevic's henchmen were ferrying their victim's corpses through Serbia - and so long as you remain ignorant of what was uncovered at Batajnica and Petrovo Selo, you'd feel secure in your ignorance, as you do now with the mass graves uncovered in Kosovo itself or the overall ethnic cleansing campaign who's existence they are a result of.
Once upon a time I devoted time to attempting to engage individuals such as yourself in discussions about this exact same topic. I found that those espousing your viewpoint were either stultifyingly stupid or actively lying and misrepresenting the facts in order to maintain their postion - ultimately, discussing the issue with them was a tremendous waste of time, and so I have no reason to believe time spent with you will be any different.
Bottom line, your ignorance and gullibility are your problem, not mine, and if you don't take the time and effort to overcome them, you've got nobody to blame but yourself when others treat you with the derision and contempt you deserve.
Bottom line, if you think all the investigators who have been there are lying, where's your evidence.
You seem to have some deep seeded hatred of all things Serb, I don't know any Serbs and don't have a dog in that fight; however, clearly you do and that might explain why you are willing to discount firsthand accounts from the left and the right, and even from foreign sources, while clinging to your own beliefs without reservation even in the absence of any evidence whatsoever. Yes, you mention “mass graves” but you and I both know there is a reason you do not provide any source document. There isn't any.
Your insults aside, I don't think you are ignorant and gullible. I suspect you know the truth, it just doesn't fit with your agenda so you simply invent your own truth.
