"how you could read my opinion piece and say I am against govt schools and for the private sector baffles me. I am not, but thanks for telling me otherwise".

Sorry for delay, I've been away; not that I expect much engagement.

My post was scathing about your academic rigour and your predictable "findings", in beating a thoroughly flogged horse, but I said nothing about your private/public/school preferences. I was criticising the "laboratory conditions' of your critique.
Where your allegiances lie is plain and hardly worthy of digital ink.
