Can Antifa save the world?

Yes.  If they stop being fascist morons.

First some background.  Bluntly so.  Antifa is a group of destructive cowards allowed to run amok in cities with Woke city councils who’ve gelded their police departments.  You’ve probably seen videos of rioting and looting occurring while the police stand nearby in utter impotence.  It is likely these hapless police wish they could intervene—in fact, they know they should damn well do so—but are prevented by their feckless leaders.  Good citizens of all races suffer, while criminals are coddled, enabled, and sometimes outright lauded.      

Antifa are among the groups and individuals who cause mayhem.  They vandalize and assault and commit other crimes.  They deny others the basic human right to free speech by disrupting speeches and protests they don’t like.  Their juvenile interference with free speech and the right of others to peaceably assemble to listen to it is why Antifa are fascists, which is ironic because they fancy themselves anti-fascists (hence the misnomer Antifa).  This is no less ironic than if Hitler’s Brown Shirts had called themselves anti-antisemites). 

That Antifa is allowed to wreak mayhem and deny people their rights with impunity is symptomatic of how our so-called leaders in many jurisdictions have abandoned good people to the harm caused by bad people.  This was evident during the riots and associated asshattery that occurred during the George Floyd hysteria.  It continues today with the Antifa and their ilk thwarting the efforts of those who speak out against transfascism.  Antifa and many other criminals are not dealt with in anything remotely resembling the punishment given to the folks involved in the January 6^th shenanigans at the U.S. Capitol. 

To the original question, can Antifa save the world?  Yes. 

Here’s how Antifa can save the world:

1. Support free speech.  Stop denying others the right to free speech and peaceful assembly.  Rather than show up at speeches and protests you don’t agree with in order to be shrill, disruptive assholes, instead show up and turn yourselves around 180 degrees—literally—and protect the speech and its attendees from others who might interfere like you used to do before you took my advice and became warriors on behalf of a basic human right (i.e., free speech).  Fight efforts to cancel speeches, especially by those you disagree with.  If necessary, safely escort the speaker and attendees into the venue if there are others behaving like you once did.  Again: Be a warrior in support of free speech, which is a much harder and braver thing to do than vandalizing, looting, and committing other crimes.  
2. Protest peacefully.  If you wish to protest, do so peacefully and without causing harm or disrupting the lives of others.  If someone amongst the protesters behaves badly, step aside and let the police deal with it.  Hell, help the police deal with it (e.g., identify the troublemaker). 

These are two simple yet profoundly important things Antifa can do, and which would have world-improving results.  I’ll keep saying this until I’m dead: Each of us—nobody is safe, believe me—is at risk of losing the right to free speech.  This is the ultimate goal of those who must divide us in order to control us.  You’ve been warned.  Again.
