(not my OC nor my OP, just helping spread the message around:-)
No offense, but this is exactly the kind of active pessimism that this post is trying to combat. The only mindset that creates positive change is active optimism. In other words, hope for better and taking action to try and get there.
Note that this is not to be confused with inactive optimism. "Everything will just work out on its own". That also doesn't work.
Active pessimism is the most damaging mindset, though, because it actively drains others of their will to make things better. Feeling hopeless is real and understandable, I've been feeling it, too. Spreading it around and shutting down those who are trying to do better isn't the way to process it, though.
