It was definitely a teachable moment when she came home and told me about her experience, and about what she could do better to express herself in an effective way to encourage change. I don't blame the dancers for taking the job, but she is still young enough to see things in black and white rather than grays. However, when through employment or conventions, many of the women who are attending (and some men, obviously not all) are uncomfortable in those situations. Especially if it is employment-related, this discourages people who are uncomfortable from being in these situations. I can't imagine an employee (male or female) having to go home to their spouse and explain why they had to take their client to a strip club to keep their job.
But, as the article is about Open Source conferences, and reading that some woman (and probably some men) have stopped attending some conferences, the conferences with issues are obviously missing the voices of those who refuse to attend, and discouraging future participation. And for every person who speaks out, there are probably another ten who feel the same way, but just silently stop attending, or change professions.
