If disproportionate representation is not discriminatory, what exactly is it?
You seem to answer your own question.
51/49 ratio among the population -> 5/95 ratio in tech fields -> 50/50 ratio at tech conferences.
Problem solved? Or did we just skip solving the problem and direct the audience's attention to the sparkling fire?
However, as I said below, I think having tech conferences with women present might be more than just a trick to pretend that the problem is solved, but actually be a tiny part of the solution.
Biologically yes, but there is a wide range of single/mixed parent families and I disagree that the similarities are far different in terms of the need to make an emotional call for attendance.
Can you claim that the demographics here are even remotely close to the demographics among tech workers?
For voluntary attendance of a 2-year old's birthday? Yes, I'm claiming that the demographics are close, in the opposite.
I'd also like the add that the demographic of thinking people is equally balanced in terms of gender, and only culture tends to swing males and females different ways. I applaud the actions of Courtney to positively encourage women to present and thereby improve attendance levels by women.
