I'm pointing a camera at you when I read the messages on my phone too. After all, the camera on the back is facing you. Doesn't mean I'm using the camera.
The "camera in my face" is just an excuse. You're actually being recorded by other things. Anyone who takes the time to learn about Glass would know that the battery would last about 10 seconds if I had the damn camera on :)
People don't actually care about the camera thing. It is a stated reason to dislike Glass, but the average person gets recorded in all manner of forms while traveling in public that it is hard to believe that the camera aspect is really what matters to people, not to imply it is the same as a CC security camera or a smartphone.
It is a small computer that's strapped to your head with a titanium band. I've worn one for extended periods, and I want to make fun of people I see wearing one; it is jarring and looks absurd. It is also socially acceptable to make fun of it, and how often is that true for something that looks absurd?
