Blimey how did asking for a bit of consideration translate into hating children?

Previous discussions on here inevitably produce the same reaction. I think there is a problem with the behaviour of *some* children, however I don't blame them but those parents who simply let them get on with it and I've seen this happen many times in pubs.
I've had one child try and climb on my lap while I was eating a meal! I suppose I should take it as a compliment that I'm not scaring them off - but when this happened the parent looked on adoringly at their offspring and did nothing - because obviously they were just 'expressing themselves'.
I'm very considerate to parents, I don't hesitate to open doors for pram users or move to a smaller table if they need mine etc but in return I also expect a bit of consideration. Is that a bad thing? And by the way, I'm not a 'child-hater'
