Covid 19 was an awakening for me. 
Never in my life was I so aware at the preciousness of being able to exchange information freely with another human being.
If people can be censored and separated from each others thoughts and analysis, whether right or wrong, if we can be cut off from the spontaenous order of unfettered collective thought, then tyranny has a free hand, and that hand invariably wraps itself around your throat. 

If Bitcoin is financial self defence, then I at least hope that Nostr is my communicative self defence.

If Nostr is dedicated to the preservation of free speech and censorship resistance, then I will back that horse.
