Dear Avocado:
Going strictly by his remarks, and having never met the man; Sherman Logan and persons like him, who stand back and make petty criticisms of the efforts of others remind me of a term we used to use in a former life in The U.S. Army Security Agency.
Persons who carped and criticized others on piccayune technicalities were given the title of “Pointy Ass”.
There aren’t terribly many pointy asses in the world, but they move around a lot, so you keep running into them!
I question Snopes too at times, but your argument is not with Sherman Logan.
Also, this site pretty much agrees with Snopes.
