In Nostr, you can criticize jack and anyone else

In Nostr, people can freely talk about and support Palestine

In Nostr, you can discuss anything, but you need to be sincere about your private key and posts

The posts here cannot be deleted. This is not any traditional social platform. You cannot cover up your evil deeds by deleting or modifying posts. So your private key represents yourself. Indeletability is the foundation of Nostr's trust network. This is the freedom world created by cypherpunks
