I suspect that the Ukraine Apologists here don’t have a problem with it, since it was a ‘misunderstanding’, don’t you know.
This is an extreme version, but such happens around the world. My Mother-in-Law is French Canadian, but she spoke perfect English. She got beaten up by French and Anglo alike.
A New Orleans resident challenges out-of-towners there to protest against the 2017 removal of the Robert E. Lee Monument. Their inability to pronounce "Tchoupitoulas Street" according to the local fashion would be a shibboleth marking them as outsiders.

In the Book of Judges, chapter 12, after the inhabitants of Gilead under the command of Jephthah inflicted a military defeat upon the invading tribe of Ephraim (around 1370–1070 BC), the surviving Ephraimites tried to cross the River Jordan back into their home territory, but the Gileadites secured the river's fords to stop them. To identify and kill these Ephraimites, the Gileadites told each suspected survivor to say the word shibboleth. The Ephraimite dialect resulted in a pronunciation that, to Gileadites, sounded like sibboleth.[10] In the King James Bible[Judges 12:5-6] the anecdote appears thus (with the word already in its current English spelling): And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites which were escaped said, Let me go over; that the men of Gilead said unto him, Art thou an Ephraimite? If he said, Nay; Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan: and there fell at that time of the Ephraimites forty and two thousand.Here endeth the lesson!
