No, they are saying that a discussion about sex and violence is going to trigger a discussion about sex and violence instead of a discussion about alignment. The irony is that trying to avoid those topics resulted in a (hopefully brief) discussion about sex and violence instead of a discussion about alignment.
I read it as "let's not discuss sex and violence for the sake of this argument because it will get a rise from people and they will hyperfocus on that and not the general issue", and let's bring up some other example that shouldn't derail people instead, but is still the same type of problem.
