Like chastise, let's say someone used the term bullet to refer to ammo, when some know what a bullet is, (see the abbrevs for an updated list) and a cartridge is. To correct one's usage of the term, to sway them to use the correct term, can be taken as the poster being snide in their attempts to do so....and that will probably mean such a post will be deleted. Get my frame of thought?
When I was in the military, one never "corrected" anyone else in public, they did so in private and here we have PMs for that.
You award in public, chastise in private.
