Apologies to the mods.
Most Marxists do not uncritically support Russia, though opposition to the Nationalists like Azov in Ukraine is something common on the Left, and believe Russia's anti-US stance is beneficial for the Global South (see the string of African liberation movements in the past few years). Most Marxists can agree that the Uyghur people have been placed in re-education camps, but most do not believe they are being systemically murdered en masse like many people report. Most Marxists think the DPRK is doing surprisingly well for a country under extreme embargoes and was subject to more tons of bombs than the pacific front in World War II, not that it would be preferable to live there than in a highly developed country free from those problems.
