10% - The guys. Yea, a bit moronic to make a private adult joke that can be heard by others in a professional setting. But even in a real job setting, they'd just get a reprimand from HR and that'll straighten most of them out.
40% - Adria. It's getting evident that she went out of the way to take offense and sees herself as Joan of Arc (superiority complex?). She tries to make herself the center of the story. Extra credits for implying in her twitter feed that every criticism she's getting is from trolls.
50% - The company which fired the guy. Are you kidding me? Unless there's a backstory or a history of such behavior from the guy, it's awfully cruel to rob a guy of his livelihood without weighing all the facts. Yea, do an internal reprimand.. but FIRING?! Crazy people heading the company.
0% - PyCon organizers. 0% - Adria's employers.
