This Country is NUTS

Maybe one of you can explain this to me. A man wearing an Optimus Prime t-shirt was prevented from boarding a flight because the Transformers cartoon character was holding a gun. Said BAA (one of the most disreputable companies in the United Kingdom):

"If a T-shirt had a rude word or a bomb on it, for example, a passenger may be
asked to remove it," he said.
"We are investigating what happened to see if it came under this category.
"If it's offensive, we don't want other passengers upset."

I simply don't see how passengers could possibly get upset by a cartoon character, but we are entering the stage where the thought police are now trying to ban drawings of things they don't like rather than just photos. Maybe this is part of the first salvo. I'm truly dumbfounded.
