If you come upon a post with a hopeful and positive message about the world or our future, why don't you take a moment to consider these things before you post a negative comment about why people should be afraid and anxious:
What is my motivation? Why do I want to add negativity to this post?
Am I assuming people don't already understand the information I'm adding? Most people are well aware of the issues facing the world, having hope doesn't mean they are hiding their head in the sand, good things exist along with the bad.
Would this be better as a post sent from my own account?
Do I have any helpful solutions people can actually engage in, that they aren't already, or am I just being a Doomsayer?
I know it's scary out there right now, and it's easy to lean towards the negative. People without hope and joy have nothing to fight for. That doesn't mean they don't care, but no one should spend all their time in the darkness, we need light to thrive.
