I read this.

And it made me think two things:

1. I do get the point of having "If you want to read it, there's a warning associated with this story". Except I also agree much more strongly with this (from livejournal, three years ago) and this from fanfic symposium: warnings are not obligatory.

2. But given that, as she outlined very clearly, a trigger may be something as unexpected as calculus - ought we all then to warn for every event in the story, since any event may be triggering?

I don't want to cause anyone unwanted distress.

But if you read my stories, you should know that I want to harrow up your emotions like a fork in butter frosting: to make you cry, make you laugh, turn you on, startle you like a thin knife that pierces your heart before you know your skin is broken, suck you in as if I were a black hole and you were my light, make you shake, make you shiver, melt your brain, make you keep coming back -

...if you want me to do that to you.

If you don't, you shouldn't read my stories.
