I am sometimes guilty of this when it comes to grammar and spelling, if little else. It irks me when ordinary words are misspelled in print and I am quick to point it out, motivated by the desire to educate rather than chide the writer.
Most recently I corrected the spelling of the word "border," as in our southern border, that had been written as "boarder" repeatedly and by several different commenters, enough times for me to realize it wasn't a typo but that's how many people think it's spelled. So I, a former newspaper writer, chose to write: "It is spelled BORDER."
OMG. You'd think I had said that Hitler had the right idea. The wrath! The outrage! Clearly I was a scoundrel and most likely a Trumpie. So I will stop doing that.
The bottom line is that I don't care if people I don't even know want to remain ignorant. Go ahead, be a dummy. In the grand scheme of things, nothing matters anyway.
