Rappelling itself is not dangerous if done thoughtfully.
Hey Conner, the reason I asked about her experience, is that as a caver or canyoneering person, even with no climbing experience, you'd be likely to be comfortable with 3rd or 4th class scrambles as an approach, know how to approach the edge of a drop-off to get to your rap, be aware of dangers of loose rock, know how to drop into a rap point below you from anchors on an edge, stuff like that. There are actually a number of routes in the Valley that fit that description. Somebody above mentioned the Van Leuven et. al. book, which lists a bunch of them. For example, with that kind of experience you might have a nice day at a place like Little Wing, which has a lovely hike to get to it and great views. And you be less likely to be met with hostility for rappelling a climbing route than you might be at an easy to access and popular crag like Five and Dime.
As to rapping not being dangerous, I agree with what you said - if you do everything right - but as far as doing things right, inexperience plays a big role too, as demonstrated by the data. Also, rappelling is subject to the same objective dangers of rock fall and rock failure that climbing is, so you can do everything right and still be in the wrong place at the wrong time.
