Maybe clarify what was actually taught before unleashing on the school......

Perhaps they were describing what discrimination was; the radical view was given as an example. Perhaps it was lost in the teaching and explanation to the kids.
I would hope that it was something like this... but still if they are broaching the subject at all, then they need to be very clear about the message they are putting across. I know my own get the wrong idea about things all the time, but teachers should be aware of this & be a bit careful ...
Will be interesting to see what the school has to say today.
