Albanians came to the Serbian land and because of their extremely high natality rate (every family has at least 10 members) and because of Serbs not wanting to live with them and leaving Kosovo selling their houses, land (safety reasons - Albanians are not harmless like they represent themselves here) they soon became a majority in Kosovo. Now they just took 15 % of the Serbian land. Can someone explain to me how is this justifiable? Thanks!

Same thing is bound to happen in Monte Negro and Macedonia with rising Albanian population.
Albanians came to Kosovo illegally and were able to do so because of the communist regime of the former Yugoslavia that allowed them.

If you would like to know more read this. It tells you all about Kosovo and drug trafficking that goes on there.
