I think this is an example of people not accepting responsibility where its due. Inadvertently fostering an environment of sexism and monoculture is as destructive as intentionally doing so. I understand that the intentions may be different but the result is the same.
Thus, it is the responsibility of every person in every industry to work hard to intentionally work against sexism or racism or discrimination of any kind (intentional, unintentional, or implied).
For better or for worse, when you have an industry as heavily male dominated as the tech one, it takes more active work to counteract the natural tendency of the industry to a masculine culture.
I am on a mailing list that spent a fair amount of time discussing the recent dust up over sexually explicit slides at the EECI conference.
One respondent wrote to the list saying that as an employee of the federal government she finds all of these controversies sort of amazing (in a negative way) since employees of the federal govt all have a very clear understanding of what is and isn't appropriate and would never show slides with sexually explicit material.
I know that everyone probably just read "Fed govt" and thought "PC, boring, and miserable" but as a women in tech, I would LOVE it if less of my time could go into being angry and frustrated, or spent trying to educate people on why things are offensive, and we could all just spend more time doing the work we are here to do: making cool technology.
We know that there are some amazing moms out there coding and killing it! And, we love them!
We made two versions of the Mother's Day site: http://skillcrush.com/mothers-day/
The whole idea is that we want to celebrate moms & encourage more of them to get in the digital game ;)
