That's right you haven't heard any complaining: because they just go to a different field to avoid it. And then all the noise eventually follows along and complains that the field is all male. And the cycle repeats.

Men are interested in doing something and creating something, and we will continue doing this forever. Those who cannot do this will continue to complain and blame someone else for their situation. A lack of personal responsibility (independent of gender) will always result in failure.
