According to an article in the New York Times:

Fredrick Brennan was getting ready for church at his home in the Philippines when the news of a mass shooting in El Paso arrived. His response was immediate and instinctive.

“Whenever I hear about a mass shooting, I say, ‘All right, we have to research if there’s an 8chan connection,’” he said about the online message board he started in 2013.

It didn’t take him long to find one.

Moments before the El Paso shooting on Saturday, a four-page message whose author identified himself as the gunman appeared on 8chan. The person who posted the message encouraged his “brothers” on the site to spread the contents far and wide.

In recent months, 8chan has become a go-to resource for violent extremists. At least three mass shootings this year — including the mosque killings in Christchurch, New Zealand, and the synagogue shooting in Poway, Calif. — have been announced in advance on the site, often accompanied by racist writings that seem engineered to go viral on the internet.

The problem, though, is that if one site is closed down, another will set up using more secrecy.   As we reported recently, Patrick Gower of Newshub spent considerable time on 8chan trying to find evidence to support his thesis about right wing extremists and found very little (having to resort to massively hyping it to compensate.)

Brenton Tarrant wanted his rampage in Christchurch to inspire others to indulge in similar terrorism — overseas rather than in NZ — and it clearly has, albeit only three successful attacks so far and in America.  He also wanted US lawmakers to ban the types of firearms he used to spark a revolution there. That part is highly unlikely, however, what might happen is greater vetting and security surveillance — which would have, of course, prevented Tarrant’s massacre in the first place.

It should be asked how much of this is a reaction to constant intemperate and provocative rants by members of the Political Correctness Brigade in America, most notably by Somali-born Ilhan Omar and NYC-born Alexandria Ocasio-Cortez a.k.a. AOC — “to every action there is an equal and opposite reaction” doesn’t just apply in physics.
