I really apreciate the time you're taking to argue with this guy, but I must tell you that it is a lost battle (if you already know this, sorry). Here in Brazil, the red-scare tactics are the far right's bread and butter (like anywere on the world). So, judging by his response pattern so far, there is a high chance that he is a hardcore Bolsonaro supporter. While some can be reasoned with, most are cannot be. Well, at least other readers can see a couterpoint.
First, Lula is adept of the so-called "class conciliation", therefore he is not a communist by any means.
Second, Lula is against the idea of a revolution, with makes him a social democrat on the left spectrum, at most.
Third, you can't just use US left as a model for the rest of the world. US left (mainly the democrats) is a pale left when placed alongside the Brazillian left, for example.
It's not like Brazil want to take sides either, so this might be a excuse, not a reason. And there is the BRICS, so taking side is not a good idea.
BTW, unlike Europe, there is no consensus here that the side to be taken is with Ukraine.
While I understand why someone may think that (just because Marx is important on both topics), they are not much related at all. The Capital is something on it's own, and Marx has the best explanation about capitalism so far.
Side note: YouTube has a policy about not questioning the results of previous elections. In Brazil, this also includes questions about the security of electronic voting machines.
Recent US elections made the people almost freak out because of the suspected Russia influence. In every developing country, not only Brazil, this is the norm and not the exception.
Bolsonaro's election received heavy support from the international (and national) finance sector. They projected a higher gain under his government. And most of these people are from developed countries.
People from rich country may not be really aware that the commodities come from somwere. The recent Russian war sure made this more clear. Developing countries are locked in that role.
If a country like Brazil, Russia or China reduces significantly its exports, everyone living costs rise. This is obviously true for high technology goods, but while you can survive with no smartphone, you can't with no food and energy.
I'm talking about this most obvious stuff to make this point: rich countries exports their poverty. USA still has a firm hand on the entire continent, and will not let it go, Brazil included.
As someone from Brazil, I really hope BRICS+ continues to grow. While the G7 can easily suffocate small dissidents, a entire block can not be. Sanctions against Russia stared to make European governments fall, what happens if you sanction half the world population?
I'm reserving judgment in the Russia's war in this post, becase most of these implications don't depends on who is right.
The american left is lagging behind in therms of political theory and this "identitarian ideology" is a symptom of that. The fact that this ideology now is being imported by leftists in other countries creates a really bad image of the whole political movement.
It is interesting that this innocuous terminological justice is now a thing in a lot of english speaking social environments (and internet), as far as I can tell, but is a joke for the majority of population (included left organizations and political parties) where I live. This is, for me, a clear sign of the elitist agenda that has minimal impact in the real life, but delight the middle-class left of american universities.
I consider myself a left minded person, and being from a third world country, I first was amused by this when this started since I do a general research of leftists movements around the world. But now that this evolved on a entire "ideology" (quoted because it has really poor political substance) and is now present, albeit not as much as in the USA and Europe, in my country, my take is that this is a dissuasive factor in the political development of the masses.
