Not just women but anyone. For any social group,the share of that group may never be at or close to their make up of the population. People come from an insanely diverse set of upbringing and social expectations.

If they think 50% of engineers should be women, I would like to hold them to an even higher standard by requiring that out if that 50% of women,each national origin,ethnicity,political/ideological upbringing and social status (mother,single,divorced,etc...) is also proportionally represented. If this is about making up for historical prejudice then let every women of a wronged group be equally represented. You will soon see the silliness of the pursuit.

It is the cause that needs policing and adjustment (upstream) not the effect.
