The original song was not about transgenderism, but about tomboys: she added trans lyrics later, which is too bad. Guess she felt it necessary to virtue signal and pander to a modern audience, since the original meaning-- that girls should be able to do what boys do-- was a good message. Unfortunately adding lyrics about implants was a quick and dirty way to update her song, and get cheers from the LGBTQ members of the audience. Twenty years from now, that message will be seen as dated, or even mysogynistic.
