While perhaps phrased indelicately, this is not a stupid question, nor should we ignore it. Perhaps msumed, you were trying to ask: "Could anyone give their impression of diversity in orthopaedics and do you think that the demographics have been changing in recent years?"
My answer to that question is that (like so many fields) orthopaedics is becoming increasingly diverse, but still has room to go. It will get there.
As far as your question about women and minorities getting a fair shake in the process, I think you should consider the question more carefully (especially within the context of a public forum). Fields are not prejudiced or discriminatory. People are. Do people exist with prejudiced attitudes? Of course. Are there any more or any fewer of them in orthopaedics than in the general population? I highly doubt it.
In the end, I would focus more on the factors that you can modify, rather than the ones you can do nothing about. That being said, finding mentors and role models is always a beneficial thing. I would pick someone with whom you relate, and if they happen to look like you, that may be another commonality, but that should not be anyone's primary criterion.
Good Luck.
