What if I have those skills, can "make everybody love me" (...) & build a wonderfully harmonious company together, but I still hate FizzBuzz and avoid anyone who uses that on me, hard pass/hard filterish-way?

As you mentioned above, you treat it as a double Bozo filter, I treat the use of it as a Bozo indicator and as "passing the Bozo event horizon in this company right now"; and my decision to walk away is like getting out of a dangerous situation with a black hole next to me.
