In the same interview with La Liberation, Tarantino is asked about his thoughts on “trigger warnings” being shown before movies, and whether, to avoid offending some people, such warnings are waranted.
As you might expect, Tarantino isn’t a fan:
I reject the word “offended”. Anyone can be offended by anything. Frankly, I think most of the time – and there are no doubt some exceptions – saying that you are “offended” by a film is the first response of a very narrow mind. “I didn’t like it, and here’s why, blablabla…” But, man, being offended? Art is no offense. And, although, in rare cases, I can understand it, it's just ridiculous to be offended by the content of a film.
He then goes on to elaborate on his own experiences. Yes, Tarantino was once offended by a film, it’s hard to believe, but he admits it. He refuses to name the film, only that it was released around 10 years ago:
Here, there's a movie that came out in the last ten years – I won't name it – that really offended me. But the more I thought about it, the more I realized that it was my problem. My fucking problem. I found it racist. I wanted to punch the director. I still think it's a racist movie. But it's just a fucking movie, man.
Which movie is he talking about?
