Regardless of what the (obscure) legal reality is in this matter, do you agree that this woman presents her case in a juvenile way, and shows a general lack of understanding of the real-world procedures (as opposed to how keyboard warriors imagine things are or should be) in matters like this, and an apparent unwillingness to learn about them, to a point where it makes her seem unsuitable to voice an informed opinion about it, and certainly ill-suited to be the flag bearer for a contentious topic like this one?
do you agree that this woman presents her case in a juvenile way
No, I don't agree. Anger at harassment and injustice isn't juvenile. Use of jargon familiar to her audience isn't juvenile either. Although I can see why others would see it that way.
apparent unwillingness to learn about them
I do agree this seems apparent.
To a point where it makes her seem unsuitable to voice an informed opinion about it
The people who filed the request are obviously trolling in order to:
1) Get the videos removed.
2) Potentially get real-life identifying information in order to enact a campaign of harassment. I would hate for GWW to be harassed. She is a breath of fresh air.
The DMCA is fine when the complaints are legit. This penalizes both YouTube and the content creator.
See how that works?
