The Atlantic, on hateful trolls finding new homes online:

this tiny group has attracted a disproportionate amount of attention in the past several years, in large part thanks to social-media platforms. Anti-trans feminists have a presence in many mainstream online spaces, including Twitter, “radfem” Tumblr, the Black women’s beauty forum Lipstick Alley, and the British parenting forum Mumsnet.

On these sites and others, they use many of the same trolling tactics as other internet-based fringe political movements to disrupt conversation, skew reality, and make the internet another dangerous place for trans women through doxing and harassment. Anti-trans activists have used social media to call out specific trans women who use women’s bathrooms, for instance, labeling them “predators” and “pedophiles,” and promising to resist them by any means necessary—be it pepper spray or pistol. GLAAD has shown that these sorts of attacks have warped online discourse, turning focus away from discrimination and instead encouraging renewed debate about trans women’s bodies.

What’s described in this article is the same online radicalisation as neo-nazis and incels.
