you could develop a response based on WTS literature that shows the more flexible attitude shown towards further education - see Nov 1st 1992 WT - Education With A Purpose

if he doesn't respond you have made your point and possibly made him think
if he does respond it's likely to be along the lines of 'new light' etc
You can then respond back with the 1969 Awake quote (saying you have been doing extra research on education policy to keep yourself off the apostaradar) - suggest to him the WTS have changed policy back and forth a few times and you are worried about being caught in the middle of a 'education is bad' period - who knows they may flip back again soon as they have done in the past?
