A woman who doesn't want to be there.
It sounds like a relatively simple answer, but I think that we go so far as to put pressure on women to pursue male-dominated careers because they are able to. I think that has a very negative impact on women.
We are all too quick to associate feminine careers as careers that women in a perfectly equal world shouldn't be in, but they want to. If they care about an occupation, they should be in that occupation, regardless of its associations.
