Sex trafficking of any sort is despicable and also in the public awareness. I'm not inclined to give credence to a film where the central character espouses Qanon garbage along with the actor who portrays him. Sensationalist rubbish doesn't help anything and there's more than enough criticism of the film and the claims being made within it. Don't like it? Eh, ain't my fault.
What is the specific Qanon claim/theory that you don't like, or don't agree with?
And weren't you claiming it was the "actor", not the character who mentioned this theory?
Since when do we boycott a film because an "actor" does, or believes, something in their private life that we don't necessarily agree with?
If the movie is opening the eyes of hundreds of millions about a very important topic, it really doesn't matter all that much what the actors believe. MANY actors are atheist, or New Age, but they make movies that cause a significant shift in the public's awareness of important topics all the time.
How is it that
you've decided the public is aware "enough" of the unspeakable crimes taking place upon children that go to the very top of the power eschelon in our world?
Has that "acceptable-to-you" level of awareness lessened these crimes in the least? Not likely.
