A Brooklyn-based anarchist group last week marked the 117th anniversary of the assassination of President William McKinley by putting up a celebratory tweet and Facebook post memorializing the anarchist who killed him.

“Anarchist Leon Czolgosz made history carrying out a famous attack on the US political establishment today in 1901. # IGD,” the anarchist group known as “the Base” tweeted.

The radical group, which actively recruits on Twitter and Facebook, describes itself as a “revolutionary anarchist center committed to the spreading of anarchist ideas and organizing.” The Base routinely organizes “prison strikes” to fight “the tyranny” of the state.

The Base has close to 8,000 Twitter followers and over 10,000 Facebook followers and uses the platforms to radicalize, recruit, and mobilize other extremists,” according to Far Left Watch. It is affiliated with the Revolutionary Abolitionist Movement (RAM), a major antifa group.

RAM is another violent, far-left extremist group that actively uses their social media accounts to organize illegal activities like the destruction and defacing of statues and the screening of pro-terrorism documentaries. They also openly state on their website that “to begin the revolutionary process, goods, land, and tools must be expropriated, or taken away from those who withhold them”.

The #IGD hashtag in the tweet appears to refer to “It’s Going Down,” a website that acts as a clearinghouse for all far-left/antifa/anarchist news. As Far Left Watch notes, It’s Going Down has openly advocated for the execution of President Trump, and for violence against Trump supporters.

They do this all on their Twitter account which has almost forty thousand followers and their Facebook account which has over twenty-five thousand followers, and they do it without consequence. While large tech companies collude to silence right-of-center influencers, far-left extremist groups like this are free to violate their TOS and instruct their followers to engage in violence.

Left-wing individuals also routinely engage in violent rhetoric online, and are allowed get away with it, while conservatives are banned for far less.

Case in point, author Monisha Rajesh, who mused about assassinating the newly elected president on Nov. 8, 2016, and was never censured.
