what you are saying could have a lot of truth ....except he wasn't first gen ...because this happened in India.
I was born in Hyderabad.
you probably found out what they were doing to female babies in the 80s before ultrasounds became illegal......that is why women my age generation in India are not really around compared to later generations when it was less one way.
I think I read somewhere that for the mid-80s .......for every 100 males, you will have an average of 55 girls. times a couple million LOL
