It turns out that it really is hard to explain some things. For instance, it is really hard to explain to men who are the face of otherwise compassionate FOSS communities how we feel about comments that they have made.
Feminism is not, as some believe, negativity. Feminists believe that they can eliminate barriers that prevent women from having the same opportunities that men do.
That is optimism. Optimism is positive.
FOSS feminists believe, for example, that with a little due care from everyone that girls, women, and other minorities can share in jokes in professional technical conference presentations, rather than be the butt of them.
Sadly, right now, this particular barrier is being tagged WONTFIX by our community leaders, but the barriers are there, regardless of whether these leaders wish to believe it or not.
So far one of the greatest tricks sexism has played, is to convince FOSS communities it does not exist within them.
