Sasori took an attack that he could avoid, it is stated by Chiyo. Kishi can make every kage female if he wants; but being kage is just a title, the things that counts what characters actually do.And just look at everybody's stronges shinobis list, they are like freakin sausage fests, even in top twenty, you can see 3 women at most. Yes, Tsunade is arguably the strongest female, but the strongest "female", so Konan, Chiyo, Mei are some of strongest females, not strongest characters; i hope i made my point; there are strong females there, but the Narutoverse full of much more powerful male characters; and the other female ninja with lower ranks are not even par with the males in their age group; k11 girls are on the bottom of the list maybe along with Kiba, Samui who is supposed to be Killer Bee's student showed absoultely nothing other than bewbz, Rin had no skills other than madical ninjutsu and withstanding some genjutsu, how the actual f**k Sakura even became a ninja in the first place etc...It is like Kishi are making some female characters just because they can play around, i am not telling every single one of them are terrible; but they are absolutely pale in comparasion...
Anyway, you seem like a cool person who has his(i am assuming that you are a he) own thoughts and ideas, which is something many people in the base lacks, i hope i did not say anything to somewhat offend you, i think it is pretty cool thing to having a debate with someone has different opinions than mine.
