I'm not sure there's a force in the universe strong enough to convince someone in the United States that they weren't, in fact, locked in their houses for 1.5 years.
The "lockdown" fantasy is so entrenched across the country that people you *actually know* were going to clubs in June 2020 will look you in the eye and say with intense earnestness that they'll never "go back" to being trapped in their house for a year.
They have to justify their current nonsense with an invented past trauma.
