Antifa would only ever target ISIS to get fashion tips. Number of humans killed is skewed by the fact that Antifa people have no real-world life skills. They have the intent to kill, just not the physical coordination. It's a miracle that the bike lock bandit didn't accidentally take out several of his own ninja pals... US homicide rate is about 5/year per 100,000 inhabitants. Assuming Antifa counts 63 million people as being a racist extremist in the USA - statistically speaking, they should have killed around 28k people between 2007 and 2016. Given that the quoted figure is only 100th of this rate, one has to assume that it's other groups doing all the killings.
