There are usually two archetypal patterns on these types of fan forums following what is perceived as a disappointing loss by the team.
(1) First wave of people venting their emotions. It's usually negative and a result of a frustrated SEEKING system in the limbic brain.
(2) Second wave of a smaller group coming in to judge the first wave. It's usually from a calmer, less emotive mind space. It's motivations can be wide and varied.
When you understand the emotional outburst of a frustrated person there is no need to come on and pass judgement on it. If people are on a fan forum venting rather than out in the world causing real harm and damage then I'm all for it. It's also easy to just understand that person is coming from their limbic brain temporarily and it will blow over. No need for the judgement at all, and to start questioning whether such supporters are really supporters.
Yes, life is short. Understand the archetypes and be aware of what your own drives are. 🙂
You missed the third type.
