That said, discriminating based on whatever factor outside of control is also idiotic. Saying things like "Women scientists are harder to work with because if you criticize, they cry" is just plain wrong. Not all women scientists are that way, and saying so or judging women scientists in general is wrong.
I wish CERN kept the slides published and opened a scientific discussion instead of hiding behind the bushes.
Making any minority(based on age, race, gender, whatever) artificially preferred is going to be unproductive to science. Science progresses by hard work and innovation and not by invitation indeed.
If a person from minority is given a easy ride just because they're minority, EVERYBODY loses. In India, where I grew up, a person from a "lower" caste(not backed by financial standing, only birth status) is given a lower standard to clear to say becoming a doctor. Which only leads to bullshit doctors. If you really care to be inclusive, make the minority groups become eligible on par with everyone else. Give them financial incentives to study harder. Don't tell a minority person that they only need to run 80 meters to finish a 100 meters race. That's just stupid.
