You can't dissuade idiots who are convinced of their moral superiority, with facts. Now stop it.
I used the exact same argument against my snowflake cousin’s husband.
It shut him up and ended the argument. Two years later, I invited him to try out a laser target shooting game. I didn’t tell him till he had it in his hand that the game was a target training tool and he had a legitimate firearm in his hands.
He did fine.
