I think he asks because the Chetniks were notoriously hairy.
basic info and some pics.
there were partizans too, but they were also not too much of the hairy type, though in s. europe people seem to have much better hair than in the north. spain, italy, greece, ex-yu itd. baldness is not such an issue there.
mr karadzic used the normal body hair as camouflage like every average criminal. thats always the first option. he or his clients better benefitted from that by emitting seriousness and confidence while practising his healing methods while being dr. dabic. ;)
