Online toxic speech as positioning acts: Hate as discursive mechanisms for othering and belonging - Esteban Morales, Jaigris Hodson, Victoria O’Meara, Anatoliy Gruzd, Philip Mai, 2025 While digital platforms foster a sense of community and identity, they also facilitate harmful exclusionary practices. In this context, toxic and hateful speech...

Toxic speech as positioning acts: journals.sagepub.com/doi/full/10.... by @jhodson.bsky.social @philipmai.com

"...showcases how toxic speech is used to define and reinforce individual and group positionality."

A complex process of "belonging & othering" often underlies "online abuse and hate."

πŸ’―! Yes! This!

Neutrality About Medical Misinformation? www.medpagetoday.com/opinion/seco... by @drkatiesuleta.bsky.social

"...neutrality is not diplomacy; it's acquiescence.

A direct line can be drawn between neutrality & even tolerance of misinformation and the current state of public health."

RFK Jr. has wide discretion to choose evidence to support vaccine decisions, DOJ argues A Justice Department lawyer argued that the HHS secretary has broad discretion to issue vaccine guidance and choose what evidence to consider.

Who needs science when you can use conspiracy theories, lies, and politically motivated spin to support your health advice?

Sigh.

Why Is the Internet Obsessed With Celebrity Clone Conspiracy Theories? Jim Carrey, Selena Gomez and Avril Lavigne are some of the stars who have found themselves at the center of viral theories circulating on social media.

Now Jim Carrey is a clone?

I've been following & writing about clone angst & conspiracies for decades.

Amazing how theme won't die. Both absurd and telling...

How to tell if doctors and health influencers on social media are AI-generated | Deception Decoded University of Alberta misinformation expert Timothy Caulfield on how tough it is to tell AI-generated doctors and health influencers apart from real ones.

Much of what they push is harmful BS, but they look ridiculously convincing.

What to know before asking an AI chatbot for health advice Tech companies are pushing new health chatbots, but experts say you still need to talk to your doctor.

What to know before asking an AI chatbot for health advice apnews.com/article/chat...

"If you’re having worrisome symptoms, skip AI"

"...approach AI programs with 'a degree of healthy skepticism.'"

Chatbots "often stumble when interacting with humans."

Does being 'manly' make you healthier and happier? The top 5 reasons the answer is … nope | CBC Documentaries In the documentary Harder Better Faster Stronger, misinformation expert Timothy Caulfield investigates if there are any health benefits to embracing traditional masculine norms.

Opinion | Why the Covid cult of ivermectin won't die There has never been good clinical evidence to support the use of this drug. But the debate over its use is really about ideology and in-group signaling β€”Β not science.

Ivermectin is making a post-pandemic comeback, among cancer patients The anti-parasitic drug became a household name during the COVID-19 pandemic, and it is now being embraced as an alternative treatment for cancer. It is as politically polarizing as ever.

Ivermectin is making a post-pandemic comeback, among cancer patients www.npr.org/2026/03/02/n...

"It became really a symbol of this sort of alternative right-wing movement..."
