456 Berea Street is linking to a great discussion on accessibility.

But I am going to take this opportunity to re-inforce what I believe is the nature of our professionalism. We should make an effort to create accessible content, because it's part of our job. And frankly, it doesn't take much effort; it's not difficult. - John "brothercake" Edwards

Nicely written, and to the point. Accessibility is the job. A lot of our clients and employers can miss the point. We aren't making these sites for them. They know the content, they don't need the site for that. We're making the site for their clients, for whom accessibility may be an issue. When we worry about accessibility, we aren't being picky, we're doing our job.
