"but women have sex organs on their chests! I don’t walk around with my pants off!"
I think what you mean to say is “women have secondary sex characteristics on their chests”, not sex organs
in which case let me remind you that your facial hair and enlarged adam’s apple are also secondary sex characteristics
if secondary sex characteristics bother you and you feel they should be covered up in public, please feel free to shove your entire head in a bag at any time
