There have been many debates and discussions on this and in this case searching 'Russia' and reading through those discussions may help. Though do not read this as discouragement from asking questions. It is, understandably, a hot topic worthy of elaboration and there are plenty of people here that will be interested in answering.

Here is my take:

Russia as a nation has a class character that is more easily compared to that of developing countries than that of a core country.

The BRICS countries, especially recently, have gained steam due to the reelection of Lula in Brazil. But also because the war, and subsequent sanctions, many countries are compelled to build an alternative to the global finacial order, aka white supremacist or "western" imperialism, giving the BRICS more vigor and more direction. Russia's role in this project is crucial. Russia may be viewed as the aggressor if you begin the story 1.5-2 years ago and ignore Donbas, but if you go back further it is not difficult to make the case this conflict began in 2014 during the coup.

The war is obviously disturbing, a major threat to global stability. It has been incredibly violent and destructive in many different ways. The war increases risk of nuclear attack, creates the surge of weapons into the region which is ending up with reactionaries committing atrocities in the Donbas region, to organized criminals and even to places much further away. Sanctions and other factors surrounding the war have caused rising energy prices and increased inflation that has hurt many countries in the global south. This is affecting people subsisting on the countryside already suffering from drought and people toiling in the metro. There is too much pressure on the masses. The war must end.

The problem is that Russia is not the only party involved and NATO will need to make concrete efforts to prove they will be able to build peace as much as Russia and Ukraine. Unfortunately, that has not played out and remains unlikely. So here we are.

I would like to add that the word "support" is commonly used in this discussion but it is not an especially useful word and by my observation is a huge source of confusion to the critics of my position and to our communities position. I do not send money to Russia. I do not send weapons or material aid. I am not a Russian citizen and thus have not voted for Putin and do not serve in the military or government. Nor have I contributed to government policy, war policy, or on the ground support as an independent contractor. Nor do I "root" for Russia as if it is a sports team or a dance contestant. Frankly, I don't feel obligated to do so either. I have my own problems to attend to.

However, what I am in favor of is the greater project that Russia is part of which is creating a needed alternative for much of the world. I think the global masses will benifit from this process of history but will suffer if it is stopped. The threat of the this development to the imperial core is the primary reason Russia is demonized for its invasion. If they were concerned about the humanitarian crisis they would act differently and pull their weight in ending it, but they hardly even admit their role.
