Yeah, I have issues with warnings. Most days I want to just not bother with them at all because man does that character death pack way more punch if it's a secret. Or that surprise pairing that is completely spoiled by the header. Other days when I'm in a mood and I know specifically what I want to read, they're useful for finding what I want. And although there's really very little I won't read, there is some stuff that does squick me although my back button does work quite nicely in the event I accidentally click. (Although I realize that's not an option for some people who are traumatized by reading about certain things in fic.)
