“It’s obvious that when debating a point, someone resorts to grammar observations and insults to demean your arguments then they’ve lost the debate and offer nothing.”
It is not resorting to grammar observations to point out that the poster was LYING when he said that Trump “harped” on the stolen election now, instead of using the correct term “mention” as he does. Pointing out the use of a deceptive word to further a lie is not grammar.
And, either you are also colluding with his lie, or too stupid to know the difference.
Trump talks about the “stolen or rigged” election nearly every time he give a speech. That’s what I call harping on it,
Talk about over the top, saying my argument is a potential lie when I don’t use the “correct” word, harp vs mention.

talk or write persistently and tediously on (a particular topic).
“I don’t want to harp on about the past”
Perhaps you should make use of the dictionary.
