I find it very interesting that Volvie, who probably, at most, knows no more than fifty non-Jews personally, is capable of making the blanket statement that non-Jews, as a rule, disrespect their mothers 364 days a year.
This, especially, since the two primary examples of Kibbud Av that we are given are from non-Jews: Eisav* and Dama ben Nesinah.

(* Yes, I know Eisav’s actual status is a bit murkier than that — but for all practical purposes, he lived his life as a non-Jew)
