I think that the media latch on to outrageous sayings be people like these because of the "tittilation" factor as has been mentioned. There's very few column inches or air time given to those Christians who say mundane, ordinary things or just go about their lives in an ordinary fashion.
It's very like media reporting of teenagers and their behaviour. It'll make the News if a gang of teenagers torch a building, but it won't if a gang of teenagers leave the youth club, go to the chipshop, then quietly go home.
The media in general gives a very skewed view on the world. A representative for Christians, if they were any good, wouldn't make pronouncements on which sects were right and which were wrong, they wouldn't condemn those who don't believe in different ideas since they would be trying to represent
all Christians. In short, they wouldn't really have much to say except "Treat others as you would have them treat you" and "Don't judge others". Those two phrases would become very boring over time and I don't see the spokesperson getting much air time.
