Most engineers are male, why do you use 'she'? Also it distracts from your other points.
Gender inequality in engineering isn't going to be solved by replacing 'he' with 'she'.
Either way, I don't think that using "she" as a gender neutral pronoun can be considered distracting advocacy of feminism.
Historically man and he have been used a universal gender neutral pronouns. In most latin languages this is spelled out clearly as proper grammar (e.g., French). In English it has been left ambiguous. That said, one clearly is making the conscious choice to swim against the tide when specifically using 'she' for this purpose, so it's going to distract some people. Though I agree far less than he/she and (s)he.
