Next time say it too him... it's fun to get in a discussion (as long as it stays civil) because they lack the facts to back up their feelings.
In Comp I, we debated the death penalty. Then we had to write an essay critiquing our performance. The point I made was that the "con" side didn't have facts, they had feelings. And statements like "How would you feel.." and "it's not fair..." aren't debating points. And once the argument became about whether it was fair or not, the subject changed and now the "pro" side was having to defend itself from charges like "would you kill a mother for slapping a mother." I told the person who said that that was the stupidest thing I had ever heard and what did that have to do with price of tea in China?
