I follow the Powerline blog, even though it's conservative and I'm liberal. Sometimes they, particularly Paul Mirengoff, surprise me but mostly not.
Today Steven Hayward writes on manners and norms in the classroom. His takeoff point is a university banning the use of titles in favor of using the students' full names when a professor calls on a student--i.e., "Mr. Harshaw", etc. He pats himself on the back for using "Mr and Ms" when calling on his students.
Call me old, call my memory defective, but I believe I remember back in the late 60's when all good true conservatives would never let "Ms" cross their lips. So things change.
