Calm down.

I'm hardly accusing anyone of any wrong-doing. It is a turn-of-phrase that I'm sure most english-speakers have encountered.

It has a very different connotation when you say "I'm stealing..." than it does when you say "you're stealing..." It's only jargon in first-person.

Compare saying "wow, I'm really stupid" when you make a mistake vs. saying "wow, you're really stupid" when they do.

Self-deprecation applied to others is just deprecation.
