Mainly with how Pan was as a character, but like they're twenty years too late to cry and bitch about
GT.
Also goes to show how little they know about Dragon Ball to begin with. There's no female Namekians because centuries prior to the start of Dragon Ball, a sudden climate change wiped out the entire race but two, Grand Elder Guru, and the nameless one who split into two when he left Namek, and those two were Kami and King Piccolo. So being left alone, Guru had to asexually replenish his race, and that's why all 109 children are all male. They're literally just clones of himself.
Although actually, it's possible female Namekians were
never a thing 'cause it's just a race of slug people with no actual gender, though it's implied they're hermaphrodites (like actual gastropods). So yeah. You'd think they'd be more praiseworthy of Namekians for being "gender fluid" instead of whining there's no female Namekians.
