I see it quite regularly on here - most recently on the Church ceremonies thread. A poster starts a thread about, for instance, toddlers being allowed run riot in restaurants, kick the back of seats in planes or whatever and you can be guaranteed that at least one poster will come back with 'well if you can't stand children don't eat out' or 'Just because you dislike children doesn't mean they shouldn't be welcome at wedding ceremonies' or 'Why should children be banned from planes just because some travellers can't tolerate them'.
It's a horrible comment to make and totally unjustified. I can't stand it when parents allow children to scream and shout in a restaurant. But I love children. The two aren't mutually exclusive.
