There exist an anti-totalitarianism flag that is not antifa?

As the title says. I'm about to start a job and I usually display small flags that represent me.

I decided to use the pink triangle as a symbol of resistance (and to welcome my LGBT students) and at the same time it's not as well known as the LGBT flag; the flag of my country with the eagle eating the snake; and I wanted to show something against any kind of totalitarianism, but I don't know if something like that exists except for the antifa flag, but that's not what I'm looking for.

Any suggestions?
