At this point there are no more excuses. What is happening is extremely obvious to anyone with half an understanding of history or the world beyond western propaganda. It's always the same pattern. These people are malicious actors pretending to be "leftist" because the spoils from their imperialism no longer exists, so they are uncomfortable about their declining material conditions, but do not want to alter their worldview too much. On top of that, you likely have actual regime trolls, since the american regime is well known for sending armies of trolls to co-opt communities it consider a threat.
