I think that putting posters in bathrooms, or even just sticky notes that say "Free Palestine" would be underwhelming although enough people doing it would probably catch attention. With the internet, it is very easy to spread proletarian news or ideas but liberals still reject it on ideological grounds and loyalty to the status quo. What are some methods of praxis or propagandizing a person can do alone in real life, without an organization, and somewhat clandestinely? Please don't say anything online would make it more difficult for you or other revolutionaries to do it successfully in the future.
Praxis can be as simple as being kind to a neighbor. Be friendly. Garden with them. When you make a pot of chili, offer them a few bowls.
Comrade doesn't just mean we're gonna get some Kalashnikova and do a revolution! It means fellowship with folks just like you, stuck in the same messed up situation, and you standing together against it.
