No, you don’t say something was like a scene out of 9/11. It was an obvious reference to the movie, no doubt.
That being said, YWN is not a filtering service. Was there a serious breach in the fact that they let you know there was a certain movie? I never watched Titanic while I was aware of it’s existance. I even enjoy its music.
The only change in YWN that I noticed is the language that used to be blocked out that became used regularly. I can’t really blame them for this. While I try to keep my own mouth clean the fact remains that certain terminology became mainstream.
