There is a danger of being simplistic about what has gone on here.
We can all strive to be, pretend to be, positive. And what would that make us? Plastic people? Grieving is a process that can't be forced. Telling people to just get over it does not help.
The conflicts on this forum of late are a direct spillover of the conflicts between the Penn group and the Football Club group. The saddest part here is that the Penns and FC have not been able to find a path forward together. The Penns have decided to crush the FC - to effectively kill it. The outcome is that many long-time loyal FC members, a core group of devoted Sea Eagle fans, in particular, have felt alienated and attacked.
If you cannot empathise that members of the Football Club in particular feel attacked when Zorba directly attacks them in the press, then you cannot empathise. An alternative is that you just openly admit that you cannot empathise with them rather than urging them to feel differently.
We are all crazy in our own special ways here. If we urge people to share our personal meaning of what it means to be "positive", then we are fundamentally being "negative" towards them.
