The dark side of open source conferences

To clarify, I don't at all doubt that there are homophobic comments, only that there would be negative events with sexual overtones (such as requesting or forcing a sexual act) by a homophobic person. I strongly *hope* that there are not violently homophobic incidences occurring at conferences, as these are the sort of physical dangers I perceive to be the problem for members of the LGBTQ population.
