Don't assume that just because parents are not on the PTA, they are taking advantage and not giving anything back to society; and actually they might have more experience of fund raising, organising events, etc than you!
Guilin where have I said anything even close to this? 
I never said that the PTA was “above criticism”.
My comments weren’t directed at helpful and constructive criticism. I didn’t even nearly imply that anyone saying “have you tried Xyz?” should hold their tongue.
My comments were directed at those people who don’t help but whine from the sidelines, moaning and bitching about how something is organised without ever suggesting alternatives.
I’ve seen the hardworking PTA Chair in tears because a stream of parents were so horrible about a bloody pub quiz when not one of them had improvements to suggest.
Apart from which in my personal experience the people who run the Twins Club, the local SEN playgroup, the NCT branch, the seniors lunch club and the pre-school play association are exactly the same women who run the PTA.
And none of them would
ever bitch from the sidelines because they know exactly how difficult these kinds of things are to organise.
