If Maka was a boy, do tu think her relationship with her dad be different?

honestly no. your thinking that her hatred for her father derives from her being a female, that's not true. she loves her mother, tu don't have to be a girl to amor your mother más than your father. anyway her loving her mother was the reason, cause they got divorced cause spirit couldn't control his flirtatious tendencies. she probably does understand where her mothers coming from being a girl, so if she changed genders she might not hate guys anymore. but i think she will still hate her father.

i think she might not hate him as much

she would be the same

well no because if maka was a boy he will still hate his dad still cuz he was cheating on makas mom!! and thats my awnser
