In this case the poster seems to have projected opinions on to a post where none were expressed. That seems problematic regardless of how they came to associate the opinions with their respondent. Maybe the poster they responded to still hold the projected opinions, perhaps that poster abandoned the projected opinions, or perhaps they thought the projected opinions distracting and resultantly chose not to share.

If I am wrong or not useful in my posts, I would hope to be allowed to remove what was wrong and/or not useful without losing my standing to share the accurate, useful things. Anything else seems like residual punishment outside the appropriate context.
