I'm sorry, but why single out Cup_Of_Coffee, when multiple other members on the board have similarly expressed disappointment about our country's handling of the situation. I think the worst you can say about his comment is that it's a sardonic joke.
Also, I can't help but blind positivity isn't necessarily warranted in this situation. The US currently leads in total infections (with thousands of infections likely unaccounted for) and people are already losing their jobs. No matter what happens, from the present moment, this crisis will have ramifications on our economy. Cup_Of_Coffee, as he has expressed multiple times on the forums, also has some respiratory issues that might make him more susceptible to this virus. I don't genuinely think that he's hoping for the worst, I think he's just trying to cope as we all are.
I get and sometimes appreciate the sentiment that we should strive for positivity in these trying times, but people also need to be allowed to express their frustration. Being honest about one's feelings is often healthier than pretending everything's great 24/7.
EDIT: I understand that it might be frustrating to see so much negativity on the forums, especially when these forums are often an outlet for excitement and joy about the theme park industry. But given the current state of theme parks, negativity is sort of inevitable, especially in a thread with this title. Until this crisis blows over, that unfortunately won't change. I'd say that, irrespective of any actual or perceived ill-intent on the part of posters, if these forums aren't currently helping your peace of mind in the current climate, it might be best to step back from this thread. I apologize if this seems directed at anyone specifically, it's a consideration I've been making as well and something I think everyone should consider if they're feeling overwhelmed by the crisis.
EDIT 2: Can't believe I forgot about the Positivity Thread:
