That's encouraging to hear, FrippEnos, but doesn't always take account of some activists' determination to "spread the word" no matter what the cost - or, come to that, the glee they sometimes show when correction enables them to claim discrimination yet again
On similar lines, it's notable that some present the possibilities with this teacher as being either "reporting a non-hate crime" or being relaxed about a child's mistake, as if there's nothing in between
Unfortunately experience teaches that there can be a lot in between, little of it good or helpful to the wider community
Actually while he's at work he can just identify as a teacher because that's the important thing when he's teaching
Edited to add this is true, @TheignT, but the kids have still got to call him something and if he wishes to make an issue of his "label" - which the school's communications suggest may be the case - other issues could follow
Much could also depepnd on whether the school were aware of his identification when they appointed him, in that it could inform what their approach is likely to be if there are difficulties
