Israeli Prime Minister Benjamin Netanyahu's son, Yair Netanyahu, warns that left-wing extremists like Antifa and Black Lives Matter, are bigger threats than neo-Nazi "scum," which he says are a dying breed.

"To put things in perspective. I'm a Jew, I'm an Israeli, the neo Nazi scums in Virginia hate me and my country. But they belong to the past. Their breed is dying out," wrote the 26-year-old in a Facebook post. "However, the thugs of Antifa and BLM who hate my country (and America too in my view) just as much are getting stronger and stronger and becoming super dominant in American universities and public life."

Antifa, as noted by Daily Wire Editor-in-Chief Ben Shapiro, "is a loosely connected band of anti-capitalist protesters generally on the far left who dub themselves 'anti-fascist' after their compatriots in Europe." But, seemingly, all Antifa does is riot and use violence to shut down the free speech of whomever they deem "fascists."

Over the past two years, notes Shapiro, Antia "engaged in vandalism, in violence, forcing the cancelation of a speech by alt-right popularizer Milo Yiannopoulos at the University of California, Berkeley; a few months later, they attacked alt-right demonstrators in Berkeley; they attacked alt-right demonstrators in Sacramento, California, leading to a bloody street fight; they threw projectiles at police during President Trump's inauguration; they attacked pro-Trump free-speech demonstrators in Seattle last weekend."

On Saturday, Antifa and neo-Nazis clashed in Charlottesville, Virginia, where neo-Nazis were promoting their vile agenda and protesting the destruction of Confederate statues. One woman was killed by a man with white supremacist ties and the two officers manning the protest died when their helicopter crashed.

Black Lives Matter, too, has become violent over the past few years, engaging in countless riots, promoting the death of police officers, and shouting down politicians. In the summer of 2016, a Black Lives Matter sympathizer assassinated five Dallas cops manning a Black Lives Matter protest.

The alt-right has seen a rise in the past two years, as well, though it's unclear how many actual neo-Nazis comprise the group. According to the Southern Poverty Law Center, neo-Nazis site The Daily Stormer grew from one to 30 chapters from 2015 to 2016, where contact is in-person and not merely online.
