Here is your answer:
Sally has not bothered to respond, but has posted on other threads since this question to him/her was raised.
Sally is a prolific poster and it is extremely unlikely that Sally overlooked it.
I would offer that this leads us to two conclusions: that Sally does not want to directly confront his/her/their misleading statements because it lays bare their lack of integrity, and second, that Sally has something to protect in so doing.
For those reasons, I believe that Sally is a sponsored troll.
That is the most reasonable explanation. And I believe that based on how often this poster posts poorly reasoned, provocative assertions, geared to solicit a reaction and a response.
Sally doesn't care that their statements are true or not, and that is secondary to simply annoying the opposition.
