How far do you take political correctness in your clipart?

I had feedback today on a course, that I thought was quite well done, that made me take a step back and get my back up a little as well. During a recent time crunch and with limited resources I put together a course for Accessibility and Customer Service Standards. I found a set of clipart that I thought looked business like enough without being too formal. I work in a health care setting and it is difficult to find (free-cheap) clipart that isn't just doctors and nurses.

Regardless of that, I took this set of clipart and tried to include as many of the images of people facing forward as I could (they were "speaking" to the learners), as many different ethnice backgrounds as I could. I looked for different levels of mobility, and I also included what I thought were different roles. Some of the more interactive pieces included real pictures of people in other roles and situations as well.

The comment that was made was that the only image the person saw of a man in my "slide deck" (not the interaction pieces) was of a man that was a doctor. Some staff may be offended by this because of the stereotype that not all doctors are men. I tried to explain there were other images of men within the course. I also tried to explain that this course was one of six in a set and some of the others within the set did have pictures of women that were physicians.

I wonder where does one draw the line. One can't possibly show every "type" of person in every single course and in fact for this particular courses I had great difficulty in finding pictures of people that have various disabilities that were not just from Special Olympic events.

Any thoughts on how you handle situations like this or try to remain as politically correct as possible would be interesting to hear.
