I was at this event. Marilee was seated directly in front of my girlfriend and I (the stage / panel and the back of Marilee's head pictured: https://imgur.com/a/GEapw). The interruptions were real. I was one of the men in Marilee's facebook post making comments about the sexism. Immediately following Marilee's comment, the entire place erupted with applause. On the way out, several people asked my GF if she was the one who made the comment, with one person saying "That was the most important thing to happen here today".
