I feel like there's some particular breed of Resetera shut-in autist that absolutely loved being able to morally condemn and look down on anyone attending a large gathering. Now that life is largely back to normal, they absolutely cannot let go of that impulse to gawk and shriek about a gathering of more than a dozen people.
How the hell do this people even function or deal with reality? It's not as if Anime Expo was the first convention after the pandemic, let alone the first large gathering. Every single day of the week you can turn on the TV and see a sporting event that has thousands of people in attendance. I can't understand where they summon this shock and outrage. Whether you think it should be happening or not, you should pretty much be used to it by now.
