“But my term “mirror image” referred to “a silly or insulting post,” which by definition cannot be the truth.”
You state that an insulting post “by definition cannot be the truth.” I’m not following your thinking.
An insult may not be a nice thing to utter - that’s why I work so hard to avoid them - but they can be the truth.
Maybe, but hardly when coming from Lost Causers' endless defense of Big Lies.
Such insults would be more like a badge of honor.
