I assume it was on threads I haven’t frequented, but I have not seen any comments I consider hysterical. I have primarily seen discussions about prepping (food/water/ammo/masks/etc.).
Nothing wrong with being prepared for whatever - hurricanes, floods, etc, Although we dont need to be like Italy, where they have stripped the shelves...
I bought some hand sanitizer, for example, since washing your hands is important. And I think cities in general should try to improve sanitation and hospital sanitation (since many people have gotten infected in the hospital).
But this is not the Zombie apocalypse and were not all gonna due. Filling your life with fear is not going to help.
