It is generally leftist. Unfortunately you are probably imagining leftist economics but they want “leftist” authoritarianism. They despise capitalism. They love state capitalism. They will excuse any atrocities and human rights violations that occur as long as the country is extremely authoritarian and pretending to be economically left.
They are historical revisionists as well. Admins are extremely fragile. They will ban you from every community for writing historically accurate facts. If you find this screenshot appalling you should preemptively switch to a different instance before they catch you doing wrongthink and ban you.
