What Alice should have written, if she valued moral clarity more, was something like, "I object to the title "Fuck Dan in the ass" written by Elliot, because it's a personal attack. I consider that immoral.
Then I imagine a conversation something like this:
Elliot: Would you consider "fuck Michael Moore in the ass" a personal attack?
Elliot: well it's nothing personal, i just think his worldview is evil, right?
Alice: ok, not a personal attack
Elliot: so the title about Dan wasn't a "personal attack" either
Elliot: cause i just think Dan's worldview, like Michael Moore's, is immoral. i'm condemning a worldview. that's a perfectly legitimate thing to do.
Alice: ok, it's not a "personal" attack but it's still wrong?
Alice would then give ad hoc (made up on the spot) reasons to object. No one would be surprised when they were bad and easily refuted. Alice would then not acknowledge this, and insist the title was immoral, because her feelings tell her so. When accused of not acting rationally she would deny it.
Notably I am aware of other reasons to object to the title. It's even fairly likely Alice would try some of those too before resorting to ad hoc arguments. But besides knowing them, I've worked out answers to them (in advance, mind you).
I'll go through one example. Some might say the title will offend readers and thus reduce readership (some will leave angrily) and thus inhibit the spread of TCS and thus make the world worse. They might suggest the solution is to refrain from writing stuff that might offend people (perhaps, "unless it was really important, but that title wasn't important"). The problem here though, is that we should stand up for our values, which allow for profanity and condemnation of bad people (at least I hope those are our values). Compromising our values to get more readers compromises our message. I mean, if we really wanted more readers, and to avoid offending people, we should probably be recommending "friendly punishments" of children or something. Of course that is a bad road to go down. We must stand firm in our beliefs, and if people don't like them, that doesn't mean we should back down or compromise in search of friends.
