filthy as the ace of spades

There's been a lot of this behavior in many fandoms lately, it seems. I think that fandom itself is really the problem - we've trained a whole new generation to think that you show appreciation and affection by ignoring boundaries, glomping, making insanely high noises all the freaking time, explicitly enacting sexual scenarios, etc. They simply do not understand that being respectful and subdued is much more appropriate. I've been hearing about this behavior mostly at cons, and I see it in recordings of panels - the fans simply do not get what questions are appropriate, or that character != actor, or that some people just do not want a hug. It's incredibly upsetting, and I wish there were more to do about it than lead by example, but I think there's more and more discussion of how this behavior is in appropriate, which may help. Unfortunately, this isn't limited to fandom - the paparazzi are teaching everyone that the proper way to show affection and appreciation for a celebrity is to attack them rather than let them live their life.
