How about the thing that you always love in childhood? Namely, Justice League of America, Naruto, Pokemon, 7 Dragon Balls... of course, you should have known one of them. Let's ask how many men there 're in JLA. Main characters in Naruto, Pokemon, 7 Dragon Balls are all male. That somehow creates masculinity in boys. Girls may not read those, but they read Moon Tailor, ... (that's all I know!). In conclusion, do you think that our gender view now was influenced by what we read in primary school?
