Other considerations also need to be processed. If weapons = warrior, then does that mean children buried with weapons took to the field of battle? Does it mean a 5 year old child was a master tailor because she was buried with the tools of the trade? There are also things like a female grave in Norway that contained a sword that was too large for her to wield. A great deal more study needs to be done before we can make any real determinations about whether warrior-women are more than a myth.
I have read three well-thought-out countpoints so far, and expect to see more in the future. My hope is that perhaps we will look more closely at additional graves (particularly those excavated more recently).
