I can't come out of the woodwork every time FOSS is targeted by trolls, but every once in awhile I have to make an exception. FOSS is like a reverse-idiocracy. Those who are easily swayed by popular opinion will undoubtedly leave FOSS for more PR-competent grounds (Microsoft, etc.). Those of us who evaluate software on it's merits, instead of the failings of the spokespersons for that software, will continue to use FOSS and reap the benefits.
But let's get back to developers. If you are angered by the sexism displayed by certain members of the FOSS community, you will most likely be reluctant to contribute to the projects represented by those individuals. Thus, any public outcry against those individuals should be welcomed, but sadly most of the outcry is Microsoft FUD in disguise, which is not aimed at the individuals, but the FOSS movement as a whole.
