I live in Estonia and i really want to participate in actual activism but there are apparent options. The only 'leftist' party here (Estonian United Left Party) is the decrepit remains of the communist party. After the 2023 parliamentary elections, the now former leader was replaced with a member of the 'right-wingers ' party by court order after getting a record of 2.4 percent of the vote that year.
They recently rebranded and are now pro eu, pro nato and dont have any mention of socialism on their website. They are at best social-democrats now, they used to be at least some form of eurocommunist but thats over now.
What do i do now?
investigate rate of exploitation in your local companies (compare profits (and debt, but thats a headache with inflation and maturities) with salary spending), people can't read financial documents in small languages
become local infographic type of guy/gal/enbipal
*also maybe there are interesting local historical figures, whose writings are untranslated, like what did local cybernetic fan in the 70s think?
