Even I would draw the line at dropping the ‘h’ in ‘historian’. It’s just plain going out of your way to get it wrong. It’s pedantry combined with ignorance and it makes you look pompous.
Here’s some informed pedantry – I heard somebody today talking about administering their Virtual Learning Environment. ‘Administer’ being a transitive verb, he almost certainly doesn’t. I think the word he was looking for was ‘administrate’.
Why bother commenting on this? Dunno really. It’s not a biggy. Just a niggle.
