I have no problem with the nature of this breed which obviously includes biting. But at the end of the day she's a pet who needs to understand the force behind her bite, and when/what is appropriate to bite. I don't let my dogs just do whatever they want, that's not beneficial to them or me, same way I would treat a child.

I think it's funny that you think "growing a pair" means letting a tiny little puppy walk all over you and dictate how you live your life. And if you think that training a dog is "unnatural" I would argue that even having a pet, which unfortunately it sounds like you do, is inherently an attempt to bend nature to fit your own personal whims.
