you see a lot "male dominated" lineups because it's a male-dominated hobby/profession. when you have 100 male dj's for every 1 female dj, of course the ratio should be the same when a lineup is considered, especially given that out of those 100 male dj's, only 1 might be good, so now break that down to female dj's and the numbers are way lower (not because theyre female, just statistically speaking).
