I'm not sure how, but that was not the intention. It means exactly what it says. I disapprove of the line of reasoning, that's what the comparison was about, not his person. It reminded me of something.
The "I'm sorry" at the end reads as if to imply downandout is (was) an abused kid.
I could see how some people might interpret it as such, but my impression was that tripzilch was aiming for a more general metaphor. The term "stockholm syndrome" might also have been fitting. I interpreted it as a general statement about victims becoming inured to their suffering to the point where they start to defend it.
