I assume you mean "I don't listen to 'women in tech' presentations", rather than, "I don't listen to women, in tech presentations". The former is a political stance, the latter is excluding an entire sex for unknown reason, even if they are talking of emberjs or thorium.
A piece of advice from my father: If you have two ways to take something, take it the nice way.
I try to follow it in my life.
Why is your null hypothesis that women shouldn't be treated as equals?
The article, on the other hand, seems to be pushing more for indistinguishability rather than equality. E.g.: "That depressing statistic about there being only three female CEOs in the FTSE 100..." It is only depressing if you think men and women being created equal means that they should have a perfect 50/50 split representation across every endeavor.
I mean women-in-tech presentations.
