Here's my paraphrased view of the comment chain:

1. stillpointlab: "I'm ambivalent about Section 230. Also [other things not discussed further]."

2. applfanboysbgon: "Hey, you can't be ambivalent about Section 230, removing it would be disastrous, any website like HN would be in shambles."

3. stillpointlab: "Websites would be OK if that happened, there would just have to be some provisions around anonymity."

5. Terr_: "Where did this talk of anonymity come from? That's not what Section 230 does."

6. stillpointlab: "Who said anything about removing Section 230? I didn't say that and I wasn't talking about that happening."

7. [Error: Recursion detected]

In other words, the thread was was steered into "what if Section 230 went away" (at #2) and your reply looks as if you recognized that and proceeded to build on it.
