I was very sorry to read that, once again, an Internet venue that might have been used to bring folks closer together has been turned to use as a weapon. Not sure why folks would want to do this. Can't see how anyone will walk away a winner in this. In other areas, on other occasions, I have worked to understand why these things occur and have had little success with this. What I have noticed in the past is that quite often what starts as a little bit of "innocent goofing" is revealed for what it is, and when that happens the individual can pull back a bit. Sometimes this doesn't happen and in the past when the individual keeps going it is because there is something else going on with that person. I can't know what the case is here. What I Do know is that often times people hate for no reason and, rather than address that issue inside, they look for "safe" opportunities to release that infection into the world. Just a few things I have observed from time to time. FWIW.
Best Wishes,
Bruce
