There is a famous story about Nobuyo Ōyama-san. While walking on the street, she saw some thugs littering, she instinctively shouted: “That's not right!” And just when she thought the thugs would get angry, they said, “Doraemon?” Quickly pick up the trash and go home. lol
Nobuyo Ōyama-san has a strong sense of justice, or chivalry, and even Doremon's dialogue was “a bit too strong” even at the time the anime aired, because the original manga was already running. been active for a while now.
And since she is an actress and also wrote some scripts herself, she is very sensitive to strong “words”. And with the consent of Fujiko-sensei, the original creator(s), she said, “We should change what needs to be changed for the sake of today's children” and some lines were adapted. Adjust to be warmer.
To be honest, everyone around her thought she was thinking too much. But when she “went out without thinking”, the gangsters said: “We can't help if Doremon tells us.”
Thugs often say nasty things to their parents, teachers and even the police. But Doraemon is their “friend”. Throughout the movie, Dora scolded Nobita, “Don't do that.” So, behind Nobita are children from all over Japan.
Through Dora, through Nobita, to the Japanese children on the other side of the TV screen, that “voice” saying “Not true” is sincerely “the voice of a friend speaking for me.”
So they might have heard, “We can't ignore this.”
Nobuyo-san's thoughts reached them.
