One thing about what age it becomes acceptable to swear: It can vary not just depending on location, it can also vary depending on your gender and disability status, and possibly other things i know less about. if you are female and/or disabled, people may want to preserve your “innocence” and may have a bad reaction to you swearing at a later age than they would if you were an able-bodied, neurotypical male. This is especially true for severely disabled people, regardless of gender.

Yes, this is definitely true.
It can also be connected to not wanting people to be able to have boundaries.
Cussing is a particularly emphatic and unequivocal form of “no”.
Some people aren’t perceived as having a right to that kind of power.
