You're focusing on the terminology and not the deed
No. It's perfectly possible to make a comment about terminology while still being focussed on the deed and the content of story in the OP's post.
Someone else picked up on the misuse of the term, and I made a comment implying that it's commonplace on MN to misuse it.
At no point did I imply or assert that this in any way lessens the seriousness of what the teacher in the OP's post has done, or that it diminishes the seriousness of any such similar crime.
People are, broadly speaking, perfectly capable of making pedantic points about language, indulging in cheap digs about the propensity for mumsnetters to indulge in hyperbolic rants, and still fully acknowledge the seriousness of crimes against children perpetrated by people in positions of trust.
I totally understand your anger at abusers attempting to lessen the gravity of their crimes, but nobody is 'deflecting' anything here.
