You know what. WOTC should put content warnings on any product that has the potential to trigger. Many people have a phobia about spiders. Better put a trigger warning on that. Many hate closed spaces. Better put a trigger warning on any cave or dungeon situation. Same for snakes, dogs, large predators, all reptiles, any situation that gets into slavery, sacrifice, any potential harm to children.
In fact, many people find violence offensive. Watch any TV show and see the warnings about that. And we can't forget all the people triggered by any form of mind control, so warnings on all charm based spells. So pretty much all of D&D should come with warnings.
I have
Ophidiophobia (fear if snakes) It is unrashinal, un controllable, and to my niece who is now 13 funny as all heck since she was 3. I also dislike looking down from heights, and can get vertigo if I am not careful. I dislike bugs, but am not afraid of them (well most but I refuse to call a fear of wasps a phobia...it is justified). I am of a fan of mac an cheese, I would prefer not to have rodents in my house. We all have likes/dislikes and fear (both rational and irational). not everything needs a warning.
If you have a yantie in your product it will not make me jump. if you have a surprise snake in a movie it might be a jump scare for me...and if it is on screen too long maybe make me apprehensive.
None of that has ever sent me into a panic attack, not once. (okay the giant deadly poison snake in my garden that my then 8 year old niece swore was just harmless as she picked it up and threw it over the fence came close).
On the other hand talk of some taboo/bad things happening to young people has caused me panic attacks. Not seeing it, not knowing the person, just the discussion of the theoretical use of it in fiction. (I am being vague on purpose).
I can't watch Law and Order SVU, and couldn't even when I like cop shows.
One of my best friends (and maybe one of the top 3 DMs I have ever met) can walk around with a snake on her, can watch SVU and talk about all kinds of horrible things that make me uncomfortable, and she can stand on the edge of a 4 story drop no problem... but I know what triggers her... and it is 500x worse then any panic attack I have ever had. I can on the other hand not imagine fearing or being upset by her trigger...
I have family and friends that survived many years in the military. SOme are fine, some are crazy, but a few have real bad PTSD... they can't even read superhero comics or watch watered down disney superhero films...
everyone is different, and we can NEVER label everything... but that doesn't mean we don't try to get the big things.
edit: mind control is a whole nother can of wyrms I may post about in it's own thread...
