Bang. Stomp. Clap clap clap. Bang. Stomp. Clap clap clap. Whistles. Whistling. The mute aren't always mute. Unless you wish to suggest that she is tied to a chair. But even then, gagging already works on people who can speak.
1. As to the first half: Those are hardly good at giving particularly detailed information, and some would be pretty hard to tell that she was even trying to get some point across.
2. As to the second: Not all of them involve successfully being captured. And let's face it, in a comic book universe, it's even odds if they'll bother to gag you.
Edit: As a counter argument, does having to cope with something imply that a person is inherently worse?
3. Yes. It's kinda in the definition of "cope". You don't cope for being extremely smart unless people in your town burn smart people as witches.
One thing I wonder though... When I think in my head, I hear my own voice going through the motions. But what voice does someone who doesn't have a voice of their own use?
4. Or someone who can't hear?
And for that matter, do I see the color red the same way you do?
1. Detailed information no, information yes. I don't consider this point refuted. Communicating something, anything can be vital.
2. Not sure quite what you are getting at. O.o
3. I disagree here entirely. Having a disability does not render a man useless for life. Stephen Hawking for instance. In a comic sense, Professor Xavier or Daredevil. One is brilliant, the other a great leader, and the third able to fight crime blind. Franklin Delano Roosevelt pulled the nation through the Great Depression despite being rendered disabled via polio. Helen Keller was still quite able to make life for herself despite being both deaf and blind. I would not dare call them worse than the average man for their contributions. In the grand scheme of things, I would actually say that they were more important then perhaps an able bodied steel mill worker in Georgia.
Having to cope with something can also make someone stronger or change them into the person they need or want to be. And there are times that people don't have to cope much, and they still turn out pretty well for themselves. But to say that someone who copes with an issue is inherently worse off than someone else is silly, especially given that they can make a life for themselves.
4. Well I suppose that depends. Do you have any visual deficiencies or such that I need to be aware of? Or do you mean symbolically, as in that I see something different in red that you don't see?
