I want to add a couple more things to this. First off I always post my prayers and condolences to the members when they are sick or have lost a loved one. Next, when there are already many posters that have offered wonderful suggestions on things, I don't feel the need to add anything to it.
People here on YT are no different than those found in any workplace or even within a family unit. We just ignore the rudness and go on from there. There are more positive people here than negative anyway.
