No, because that's basically putting fuel on the fire. Whoever did it knows the wrong, and has their choice to make about how they treat people. As well, this is about two years ago as well, and a lot of things have changed since then. I'm not an active part in the tournament scene, or even the community really, so it'd be of no right for me to "point fingers". Out of my years in and out of the community, I've only had two people that I've really found "problematic," both of which I have voiced quite well in the past, and quite childishly.
It's neither here nor there for the details. The point is that we as well versed members should not treat people that are new to the scene that way. I'm all for corrective action when things like that do happen, whatever it may be, but it's far better to have preventative action when able, and the latter part does not happen unless it's discussed. The more vocal members, though, have not had a desire in the past to make a change in the "attitude" of the group.
TL;DR version - The reason the scene is dying is because the actual human character of integrity and respect in the scene is dead. Unless that latter portion is revived, the former will remain as is.
My view is that the latter will still be dead though, because those who could REALLY work on improving that, are either too prideful or ignorant to actually realize that, since they are in the "now" moment and can't get outside of themselves to really see the future. A stain on a new shirt sticks out far more than the shirt's crisp color.
