I was proud of how politely I explained to a cow-orker that his comments on victims were borderline shaming, and it made him rethink. I politely told another worker that something he was repeating from a popular web site was only partly correct and thus misleading, and he said "well that changes my whole perspective on ___."

This year is making me improve my skills at politely explaining wrong things. It works so much better than just telling people they are full of ****. :-)

And yes, The Battleship Potemkin has some unexpectedly cool imagery!
