Your use of the term "willfully ignorant" is disingenuous. People are not choosing ignorance, but rather they are choosing to enjoy a work of fiction, as I stated in a previous post, as a blank slate. To naturally encounter the prose as the author intended, instead of having it revealed, piecemeal, by another. Is it really so onerous a request to ask that you only openly post spoilers in threads that are tagged as such, or use the spoiler facility of the board to otherwise hide what you're revealing from those who don't wish to see it? I agree with the others who are saying that it's just a respect thing.
