My argument actually is not for the first part of the BtN entry: "From a surname meaning "one who dyes" in Old English.", which I am not really familiar with, but for the second part of the entry: "It also coincides with the Latin word dexter meaning "right-handed, skilled", which I know is wrong.
What I am doing is providing actual historical information about the name Dexter
in ancient Greek and the very first usage of the name in Greece.
"Until the day that an ancient inscription will be found with the name "Alexandrovski" written on it instead of "Alexander
", true Macedonia and true Macedonians will remain Greek, as they always were."
