What can be more childish than laugh about people when a preview comes up? What the complainers did was not unpleasant at all, it wasn't really angry or disrespectful in any way. It was simply a stance toward a certain action, or the lack of.
And these boards are meant to show one's opinion. As long as the opinion is not disrespectful to others, it is fine. What was highly disrespectful was your redundant comment. Again, this is just my opinion. You can of course disregard it as surely as I will disregard yours.
