Can you name any person who publicly registered any form of annoyance reading the old name, prior to the movement to replace the name?
Can you cite any person, before, during or after, who gave a valid, coherent argument as to why the old name should annoy anyone? (Or are you willing to attempt one yourself?)
Note: the two arguments I am familiar with boil down to "it could be understood as describing a bad historical event, and ipso facto must not be uttered", and "if I am annoyed by something then that is inherently valid and you lack standing to question me, on account of my identity characteristics". I don't accept either of these as valid, for hopefully obvious reasons.
(And in fact, I can't recall actually ever seeing the second argument deployed honestly. I can only recall seeing people not of the relevant identity characteristics presuming that they were defending people who would feel that way.)
