Let's get a couple of things out of the way before this goes where it shouldn't.
Most people don't know the difference or care to and therefore it's not important.
That simply is not a logical conclusion. Not knowing or caring about the difference does not make it unimportant. It makes it unimportant to those who don't know the difference or care to know. A slight difference with huge meaning. Also, I suggest that most of those that don't know the difference do care, and once they know they are incorrect appreciate being told about it.
I will never quite understand how we got to the point that correct terminology is
anal. That is like saying, "Some people just don't know how to act."
Waitaminit! That's actually true!
Perpetuating false terminology is perpetuating ignorance and sloth. It also condones the attitude that it doesn't matter.
If terminology doesn't matter, then drive your shirt to work. Then tell everyone how good it drives.
Some teaching moments are also learning moments. Some are assuredly not.
(Edited to add: Some people are indifferent to their ignorance because they are unaware of any effect on them. Some people are sensitive to details, including terminology. Calling someone who is detail-oriented, anal, is reverse snobbery. It also does nothing to eradicate your own ignorance. Remember, the truly ignorant person is unaware of their ignorance. All this has nothing to do with those that harp on a simple detail that is of no consequence. The trick is to know the difference. Handloaders learn the importance of these details right away.)
