Argumentum ad lazarum

Helping orphans the way you would do it
Argumentum ad lazarum is the logical fallacy of thinking a conclusion is correct because the person making the argument is poor.

Example:
Hermits are wise, they are not distracted by possessions.

The opposite is the argumentum ad crumenam.
