I fail to see how skin color, gender and "safeness," whatever the hell that is, implies someone has a "reduced" ability to detect and solve important problems. If you actually look for it, you will find many examples of people with the superficial characteristics you describe, and find that not only are they an extremely "diverse" group of people -- in the characteristics that truly matter -- but that they are doing precisely the kind of work that I think you speak of.
Why stop at people in "our field"? What about all of the people who possess the superficial characteristics you mention, but who also share an extraordinary amount of "diversity" and have had extraordinary success in treating important problems -- outside of "our field"? Doctors, scientists, engineers ... all over the world ... truly seek to make the world a better place.
Frankly I'm sick of the notion that "white, male and safe" implies a lack of diversity and a lack of ability or desire to detect ... whatever problems you have.

Edit: To be clear I used those examples because they are the majority in America (which I should have been more clear about) in an effort to point out that the majority often does not pay as close attention to the problems that arise from being in a minority.
What you said was both racist and sexist. You're saying that a group of people (based on race and sex) are "not going to ..." do something. Speaking in generalizations using these classifications is generally regarded by most folks as racist/sexist.
It can be tricky though. You might be right, but you'll still be called out for it. For example, the peoples of eastern asia are statistically less tall than their counterparts in western europe. Nevertheless, "asians are shorter than europeans", is still a racist statement.
Unless you can see, as well as explain, how the generalizations you're making benefit the conversation, it's probably best to avoid making those types of statements in the first place.
Racism itself might be "wrong", but that doesn't mean you can't be racist and still be "right" in your assertions. That's the tricky part.
"Racism" (note the -ism to denote a system) requires a social, political and/or economic system by which a dominant group retains power over other groups. By that widely-held definition, it's literally impossible for a non-member of the dominant group to exhibit racism.
