There are some people who would have no problem stealing your money. Turn the argument. Ask if it is OK for you to steal money from the person you're questioning. Ramp it up as before. Push the outrage button. Let that person understand the sting of theft instead of trying to tweak a guilty heart string that may not exist.

Depends on the sheeperal in question.
Most of them derive their righteousness by their advocacy.
They want to think of themselves as “a good person” and don’t want to be called a thief.

So, in the majority of situations, my angle would be better,
but there would be the fringe cases of folks that have no problem stealing from others, but wouldn’t want to be stolen from.
