Even so, if the post starts with an obvious falsehood - unrelated to the topic at hand, the rest has no merits to me. It's written in bad faith.
A talk is not a logical proof. A wrong phrase does not imply everything else following is wrong.
Seem silly to dismiss the 2nd phrase because you disagree with the 1st.
But sure, if you wrap it in fancy talk, it almost sounds like you are right.
