You cannot give specific figures for the past 50 years, but there are differences. There are families with 12 children, but there are many other families with 2. It is a part of the culture and that is what people decided to do. There is no conspiracy theory that they made babies in order to do something against the Serbs. In fact, one sad thing that I often heard was that mothers would say that "three of their children were for Milosevic, and the rest for her" prompting that those for Milosevic would be killed at some point. But I do not want to get into that discussion.
My only point in these comments is to create some kind of balance to your comments, as I regard them quite belligerent. I understand your attitude and your idea of the Albanians and why it is such, but I am trying to give you some truthful information of what it really is like.
BTW, I am sure that you are very aware that "Shiptar" is a derogatory word (very offensive actually) and would be considered a snark.
