I partially agree with you, but also with the rest here. Yes, as people, we should be united fighting against the elites which don't let us live the life we deserve (because we are receiving less than we should considering our productivity, and because many problems can be solved already). We are all on a planet that we need to save, even if only for selfish reasons. We should be together. But the elites have seized the opportunity to divide us with ideologies such as economics, identity politics, etc. If they need an unfair war against a country to exploit it and extract its resources, they'll say it's about patriotism or security or something like that, and many people will believe it and support it. Just look how divided we are about current affairs.
The left usually goes against these interests. Thus the red scare, the fake leftists that only makes us look bad, etc. They need to disband the left, and they have an army willing to do so for free. Here's where these opinions enter. As long as an elite, yes, but also all their supporters go against us and against basic ethical principles, we cannot sit and say: "people, do not trivialize wars on social media, it is not nice", "oil is cool, but saving the planet is cooler", etc.
I believe in stronger actions, for example, the sabotage people are doing against the shipping of weapons that are meant to kill civilians in Palestine or the blockages against deep sea mining. These are actions that can save lives without actually hurting others as the economical damages are not going against individuals but big institutions that can manage the losses.
I also believe in dialogue. I actually dislike how we stop listening to each other as leftists: how moderate, often liberal-leaning leftists censor radical leftists such as marxist-leninists ("tankies") or gender critical feminists ("TERFs"), without listening to them. No, they do not necessarily promote hate and they have valid points that may need further exploration. That said, I believe in the censorship of hate speech, explicit hate speech like the videos circulating about how others deserve to die or deserve to suffer. That's unacceptable, no matter the group of people you are talking about. Indeed! If we say that we need to kill white supremacists, it is no better than them saying they need to cleanse the population. Still, we need to keep their hate and all hate out of the normal discourse and we need to defend ourselves in case others turn to violence.
In a nutshell, it's about defending the wellbeing of beings in the most peaceful and civil way possible. It is about defending ourselves while doing that, because the people in power and their supporters won't often like it.
Do you want a crude example? Read about the people defending the wild life in Mexico. Politicians and organized crime want to profit off those lands. They rob lands from people, often indigenous people; they get into illegal or non-sustainable logging; they enlarge the black markets, hurting and endangering populations; they transform regions, affecting the whole ecosystem. There are people, usually biologists, who warn against this and dedicate their lives to the protection of the forests, rain forests, etc. They end up dead. It is very dangerous to protect the monarch butterflies, the wolves, the big cats... Isn't that ridiculous and terribly sad?
This is how it has been for a long time. Speak words of freedom in the kingdom and you might lose your head. Stop the machines and they'll justify killing you. I mean, read Lord Byron's defense of the luddites and then think about how they dismissed it...
Personally, I do not see rightists as my enemies, I see them as people tragically going against others' and their own interests. The ones that are in power are blinded by it, and the ones that only follow are blinded by hope: "Someday I'll be rich, if only I defend the status quo a little longer".
My personal enemies are the horrid ideas, feelings, and values that accompany most of these acts I disapprove of. Selfishness, vanity, etc. Some people, many people (I am no exception), naturally tend to them in varying degrees, and I can only feel disappointment for the number of people that embrace them. That leads me to my secondary enemies, the things that make people do not defy them. Cowardice, apathy, dogmatism, etc.
Edit: And I do not have final answers. I do not know if we are in need of a revolution, a reform, an extinction, time... I know very little.
I am very sorry you got caught in one of my rambling, ranting comments. My point is that it is not a situation in which two sides are equally wrong, but a bunch of the population that sides with the tyrants you yourself allude to in your comment. People who still deserve our respect; that respect doesn't mean passivity when they actively affect others.
You are absolutely right and we need to fight against corruption and many other things, and that's why I consider myself a leftist: you name it whatever you like. These are my attempts at rationality and correctness, and, while I might be a minority in the details, I know I am in good company in the broader ideals. Many of us disagree in a very trivial way... Sorry, and thank you for reading this far.
