[..] There is nothing wrong with allowing people to push ahead based on their talent. There is everything wrong with you locking them out based on their sex or race.
Just like the examples given, most of the fasest sprinters in the world may be black, but that doesn't mean every black man can sprint faster than every white man. You are better picking your sprinters based on ability rather than colour.
Equality is all about juding people on an equal basis. Equality is not about letting female fire fighters have an easier exam to even up the numbers. Anyone who thinks the latter is hindrance to true equality and only ends up repressing the majority.
This, exactly. Everything should always be based on relevant ability at an individual level, not on whatever group-based stereotyping has the most power at the time. If that leads to an unrepresentative grouping on the basis of any irrelevant factor that's considered important in that society at that time (sex, "race", whatever), then it's a good idea to check that the selection process actually is based on relevant ability at an individual level. It might be because there genuinely is a correlation. Or it might be because there is unfair discrimination at some point. Maybe not at the selection process itself - e.g. a university that based entry to maths degrees on relevant ability 100 years ago would have ended up with almost all men. The unfair discrimination would have come long before the university's selection process.
