Notice that halfway through the article there's a photo of a smug moo using her kid to babystalk the passengers behind them, while the woman stuck sitting next to them is staring out the window to avoid them.
I love the quote underneath said photo, which says "Clarkson argued that his children did not fly until they were old enough to behave."
So that's why Moosnet is up in arms, Clarkson is actually a parent who makes sure his kids behave. He's not letting his kids run wild and bug the other passengers, all the while expecting the other passengers to coo over his hellspawn and find their shitty behaviour adorable.
I think I'm starting to like this guy.
