How is it one group of people can perceive something one way, and others in a totally different way?

This picture of a toddler flipping someone off seems to tickle some funny bones. It pisses me off. I don’t see it as remotely cute or funny. I see it as an utter failure of parenting. A fb “friend” posted the above link along with a winky smiley face. ;) I posted, “I’d turn that kid over my knee.”

How could anyone see it as cute?
