What is also at issue here is the notion that somehow kids can't take in stuff 'out of the ordinary'.
I have been in a civil partnership for 6 years, it is our anniversary today. There were a number of youngsters at our ceremony, whom the parents chose to bring along.
None of those youngsters were alarmed or shocked when the two grooms kissed. This is simply because they are not taught prejudice.
Kids find it easier to take on diversity issues than most Daily Mail readers,...
Presumably if the kids believed that their teacher making this change was just a normal thing in life that happens from time to time then they wouldn't be anything that could disturb them. It's only if an adult suggests there is something 'wrong' when their sense of stability in threatened. Therefore handled correctly (which probably means just being really low key but answering the kids' questions IF they ask them) there would be no concern. Therefore it is the adults that have the problem themselves that would have caused the problem for the kids.
Littlejohn would be such an adult along with the Mail readers who obviously enjoy his column and the generally unpleasant bigotry spread throughout the paper they buy.
