> I realize a line needs to be drawn somewhere, and in this case that line was chosen at me. When you're the only one to cross a particular line among many other people, don't be surprised when you get called out. The lines may be fuzzy, sure, or it might be a pretty clear-cut case (such as, smoking weed in a crowded audience during a tech talk), but regardless you should try to have an idea of how your actions might affect those around you. As a thought exercise, ask yourself if it would be okay for everyone to be doing what you are currently doing. Say, heckling the presenter, or using illicit substances, or even just talking to the person next to you. If an audience full of people heckling, smoking up, or chattering to each other would be counter-productive to the presenter's ability to present and/or an individual's enjoyment of the event, maybe you should consider not doing it yourself.
