For me it’s detailed describtions about people’s dreams.
Not only doesn’t your story make any sense, but you’re also telling me about something that didn’t even happen. It’s kind of like telling about an event, and then ending the story by saying you just made it all up, except with dreams you begin by telling it’s all made up. I’m already not interested before you even started.
Nutrition and diet stuff.
(And here I go, talking about the stuff I don’t want to listen to other people harp on about! Haha.)
It’s mostly because I used to handle regulatory documentation for a food company, and as a part of that I read a LOT of mommy blogs/health blogs/etc. and discovered people are shockingly uneducated about the actual science of nutrition–but more than happy to talk about their ignorant misinformation at length, and gather followings online for it. People are also uneducated about the history of nutrition and food regulatory agencies and say a lot of stupid things there too.
You kinda see the same sort of problems arising that caused the anti-vaxx mindset. Anti-vaxxers come about because vaccines were so effective at preventing once-prevalent childhood diseases that people grow up without actually knowing people who got sick from those things, and they start tilting at windmills instead due to a lack of personal experience with the deadliness of certain diseases. (They attack the vaccine helping them, instead of having the experience to be scared of the disease.)
Likewise with food, food safety with pasteurization and such has been SO effective that you have things like raw-milk advocates crawling out of the woodwork because they’ve never actually heard about a toddler’s kidneys being damaged for life from salmonella. Apparently to them, their “freedom” to eke out…oh, some tiny unconfirmed extra “nutrition” from unpasteurized raw milk…somehow outweighs the very real risk of actual human beings becoming ill and dying. But historically back in the day tainted milk was a very real danger, killing kids and elderly and making others sick, it was a public health menace. The discovery of pasteurization was ground-breaking because it fixed that public health issue. But people who don’t know their history and haven’t seen with their own two eyes someone getting really sick from raw unpasteurized milk get fixated on some hypothetical damage being done to them or their freedoms if they can’t get or drink their raw, unpasteurized milk due to laws or regulations. They’re completely willing to let real people die on their minor molehill. Mostly because, as with anti-vaxxers, they haven’t seen what life is like when people are getting sick left and right from this stuff.
I also come from a background of trauma and abuse, and I’m extremely aware of how quickly control of food by someone antagonistic towards you can physically make you ill or sick very, very quickly. A lot of people have hot takes they think only affect them but which can fuck up other people if they were applied more broadly. There’s this disconnect that food is actually needed for people to live…probably because the people flapping their gums have never missed a meal.
