Why is there no similar push in any other field (think firefighter/truckdriver/constrution)
I think it is across the board (of course only when male numbers are "too high"). Female-owned construction companies are preferred for government contracts, and the NYC fire department just eliminated physical performance tests since not enough women could pass. It's probably happening now because the tipping point of unmarried female voters has been reached, from now on they are simply going to vote themselves entitlements. The writers of the Constitution weren't just being jerks when they didn't give women suffrage
Women are shamed and punished and shunned for life when raped in India
If that's true, they are probably a lot more cautious. Impossible to be raped if you aren't within striking distance of the penis.
