Agree wholeheartedly, Leveller. The best events are those which are all-inclusive, and where -isms of any kind are discouraged.

However, it's undeniable that there exists a certain kind of parent whose obsession with their own children reaches such a pitch of besottedness that they are incapable of recognising when the behaviour of their children is detracting from other peoples' enjoyment of an event, and who take great exception to this being pointed out to them.

So maybe the answer is to encourage that kind of parent to recognise their childrens' failings and take responsibility for their behaviour? In that way, the objections of adults to child-inclusive events could be forestalled.

I say this from the POV of a 63-year-old parent of two boys (now adults!) who took them with him everywhere he went (and that was to a lot of places and events, of all types) but who always tried to ensure he kept firm control on them when they were wont to behave badly or in an inconsiderate manner (as, indeed, all children do from time to time).
