The person who messaged me said he was attacking him because he RoR'd (that's fair enough) but then went on to say that RR didn't know how to play..used all his turns, spent his stock, never finished above $15 mil, etc....so he was also attacking to teach him a lesson. How does that teach someone how to play?

I do stupid stuff sometimes, too, but attacking me won't turn me into a top 10'ner. If it would, I would dump my defense.
