Possibly the thing that disturbs me most about that comic is not the dog/child sex story but the fact that someone decided to put his/her full name on there.
The way you say that, it makes it sound like if it was not at all a comic about a dog/child sex story, you would still find it equally disturbing that someone decided to put his/her full name on there.
Like if it really, REALLY was the one thing that disturbed you the most about that comic, then any other thing that also disturbed you about that comic should be completely irrelevant to the context of that one thing you found the most disturbing out of all disturbing things about that comic.
The one thing I found most disturbing about that comic was that in the context of a universe where dogs are 100% capable of enunciating the human language, that the dog is more capable of giving actual consent than the child.
