I didn’t say anything about female engineers in general in my comment or compared them to Americans. So I’m not sure which part is “nonsense” which you are talking about.

The reasons why there are more females going into engineering in India and other countries on the developing side like Romania have been well discussed on HN (yet the pattern of women not being as frequently in math or engineering remains in many developed countries, hardly just the US) I don’t think it’s particularly unique to India or Indian women.
