Good, close-up look at Terrorgram's accelerationist grooming process, using the kid who attacked an LGBTQ+ bar in Bratislava, Slovakia, in 2022 as a kind of case study. (Apparently the authors of this article have been working on a Frontline doc about this stuff that will be out in a couple of weeks.) Worth reading.

And so in August 2019, Juraj Krajčík, then a soft-faced 16-year-old with a dense pile of brown hair, immersed himself in a loose collection of extremist chat groups and channels on the massive social media and messaging platform Telegram. This online community, which was dubbed Terrorgram, had a singular focus: inciting acts of white supremacist terrorism.
Over the next three years, Krajčík made hundreds — possibly thousands — of posts in Terrorgram chats and channels, where a handful of influential content creators steered the conversation toward violence. Day after day, post after post, these influencers cultivated Krajčík, who lived with his family in a comfortable apartment in Bratislava, the capital of Slovakia. They reinforced his hatreds, fine-tuned his beliefs and fed him tips, encouraging him to attack gay and Jewish people and political leaders and become, in their parlance, a “saint.”
On Oct. 12, 2022, Krajčík, armed with his father’s .45-caliber handgun, opened fire on three people sitting outside an LGBTQ+ bar in Bratislava, killing two and wounding the third before fleeing the scene.
