Is it Wrong to Kiss Your Five-Year-Old on the Lips?

Why is this picture making people freak out? Because she's kissing her daughter on the lips. Her daughter. On the lips. This is a big deal?

How is this a big deal? Can anyone explain it to me?

She's not making out with her kid. She loves her kid, it is the kids birthday, she gave her a kiss.

Some comments on the picture...

briandavidmitchell: This is disgusting

the_hudsonriver: My question is why isn't she wearing a shirt?

heavyg: Eww sorry, I'm old fashioned, it looks like they're making out.

one__34laforever: That's one passionate kiss right there. Hope she gets so passionate with David Beckham.

I can't even with this.
