Garden variety misinterpretation. Nothing new. But the characterization of me as "taking offense", is interesting.
The important thing to note, I'd say, is that the misinterpretation is at bottom a device to compel attention:
The normal response to being misinterpreted is to assume the error is benign and to try to clarify things. The S-E sufferer exploits this response in the manner you see here.
I'd depict the "schema" of the ploy as:
S-E states a hostile mischaracterization of the target's post.
Relying on the target's supposed desire to be correctly understood by the S-E sufferer,S-E uses the proposed misunderstanding to deliver other hostile material.
The premise is "If you want me to understand you, you'll have to read through the post which exhibits my misunderstanding, so I can use it to strike more blows."
Sooner or later the whole thing breaks down because it becomes apparent to the target that the misunderstanding is not "Real" but is an, in some sense, intended device or "game" -- or, more precisely, a "move" in a "game".
He made a pit, and digged it, and is fallen into the ditch which he made. His mischief shall return upon his own head, and his violent dealing shall come down upon his own pate. I will praise the LORD according to his righteousness: and will sing praise to the name of the LORD most high." -- Psalm 7:14-17"Behold, he travaileth with iniquity, and hath conceived mischief, and brought forth falsehood.
