I’ve read them, and I understood the context back then differently.
In my understanding, the context of that discussion was @strokeybeard trying to gauge what level of Nazi-ness was required for other people in the thread to support punching. Someone said that Nazis who attack other people people deserve to be punched. Someone (don’t remember if it was the same person) said that self-declared Nazis deserve punching (in response to some claim that people might get misidentified as Nazis).
In that context @strokeybeard pointed out that Spencer fulfilled neither of those criteria in the video, i.e. in the moment he was punched. To me, that is a request to further clarify the criteria used, not a claim that Spencer is not a Nazi. In that context, it was a question about how obvious a Nazi someone has to be in order to be punched, not a defence of Spencer.
And yes, repeating the same bad argument with no acknowledgement that you had been corrected does imply a level of support for the side you are falsifying the information for.
I don’t see your correction as in any way contradicting (my reading of) what @strokeybeard said.
The whole thing looks to me like this:
Person X: “A.”
Person Y: “How can you possibly say B? B is not true!!”
Person X: “But I never said B, I only said A!”
Person Y: “You’re doing it again!”
Person Z: “B is false! You’re an evil person for saying B!”
Person X: “A and B are not the same thing. I never said B!”
Person Z: “I don’t believe you! You’re still saying B!”
Person Y: “You keep repeating something that has been corrected over and over again. Obviously you are a dishonest person supporting B!”
And in fact “A” is an easily provable fact that was only relevant in one context which is long gone. Reiterating “A” out of context indeed makes one look like a person who would say “B”, but in this case Person X has no other choice - they need to reiterate “A” in order to defend against the worse accusation of having said B.
Maybe it would help if you formulated concrete statements that you would like @strokeybeard to make or to explicitly distance himself from? That might obviate the need for further discussion of “I never said it” - “You’re saying it again!”.
