1000% this. I'm now rediscovering my rather fluid gender identity and attraction to both genders that started in my late 30s. Looking back, all the signs were there, I just kept things private as it wasn't socially acceptable. Had some outlet with the teen goth scene, which was nonexistent in college. Grew up in a heavily catholic influenced region.
Have an awesome wife who is supportive and revealed she is (now was) also closet bi from the same generation.
We moved away from there, but when I visit family all the churches are run down and closed. I smile every time knowing their grip is loosening. All the LGBT hate today just tastes like desperation.
Soap boxing here but I feel these kinds of use cases is what NixOS is built for.
Declarative config to setup the system, users, and apps.
Declarative and customizable impermanence exactly how you want it.
I use Tails as well but NixOS is my daily driver. Anything not marked explicitly to persist is dropped each reboot. I'm the only user so I keep the last 30 days of non persisted data for like a power outage but that's something I had to go out of my to setup for my use case.
