Every single thing @pcloadletter:disqus says about the reason for despising spoilers is 100% spot-on. "Well, you should have known Walt would die anyway." is diversionary b.s and intellectually weak-sauce. No, we didn't know Walt would die at the end, watching the show. We might have suspected. We didn't know. …

We don't tell people the plots of movies we have seen, if we know someone wants to see it. That has been considered rude since movies have been a thing. It is rude. People who do it are rude people, full stop.
