Re: I am confused
I'm not sure if you genuinely don't understand or if you are, as I suspect, simply determined that I must be wrong. To extend the benefit of the doubt one last time:
It very much does have to do with sexism. I provided good quality primary data showing that computer classes have higher female participation in sexist countries than they do in less sexist ones. I even helpfully directed you to examples of both countries as the data set is large. The reason for this is because in these more sexist countries, women have less career choice. You're less able to become a doctor or a lawyer or a manager, etc. When choice is restored, e.g. Sweden, you find participation drops because more often than not a female student will pursue a career other than a purely technical one.
The first are well-demonstrated facts. The conclusion is directly derived. If you again try to shift ground or dispute this, then I don't believe you're arguing honestly.
