Name any Communist nation in modern times that has ever achieved this alleged aim of Communism.
There has never been a Communist nation in the first place. "State Communism," on the other hand, very much exists and is a right-wing perversion of communism that adopts a few of the elements as a flimsy facade. Totalitarianism is problematic, whatever the disguise, and pretending the sins of Totalitarianism are the sins of Communism is a defense of Totalitarianism. Any chance that you'd be willing to stop defending Totalitarianism?
To be clear, actual Communism at nation-scale is likely still not doable in the first place and human nature would likely quickly doom such even if the hurdles could be overcome. There's plenty of criticisms that can be made about actual Communism, in short, but what you're forwarding are not that.
Let's not worry about all the damages and injuries and deaths Antifa caused!
So far, you've reasonably established that antifa caused injuries when they fought back against the very right wing Proud Boys picking a fight with and attacking them. Such incredible reasonability!
Damages? You've repeatedly tried to engage in extremely dishonest sleight of hand when it comes to your claims. Who actually did the damages that you claimed and the actual nature of those damages are things that you just keep casually ignoring as you try to blame your preferred targets.
Deaths? Kyle Rittenhouse alone accounts for more murders than all of Antifa during the BLM protests! In general, during the BLM protests, right-wingers were the primary killers, yet you keep trying to blame antifa and the left-wing for the actions of the right-wing. On top of that, Republican legislatures outright passed bills to pave the way for right-wingers to murder protesters! Yet you still keep trying to attribute everything bad that happened onto Antifa and the left.
The fires were significant, millions of dollars in damages. You wouldn't be so carefree if it had happened to your property.
You cited an article that said that firebombs were thrown at the police. That's very, very different than the city being burned down as you claimed. You've also effectively argued that contents of a trashcan being burned counts as buildings being burned down.
The dishonesty and misrepresentation would be staggering, if you hadn't already shown that it's to be expected of you.
As another small side note that you may reject because it conflicts with your preferred narrative, for the protests, the actual BLM organization trained their people to do their best to keep everything legal, non-violent, and with no property damage done. Mostly, they succeeded. Yet you vilify BLM as a matter of course.
