How do you tell the age of cartoons?

This is regarding to loli controversy in several countries. But how can you actually tell the age of cartoon characters? Is it even possible? How old do you think the girls in pic related are?

And more importantly, who's got the best butt?

Fuck off for the 33⅓ time.

muh dick knows when they're old enough or not

So what about the OP girls?

It's been too soon since I've fapped. My dick doesn't even care yet.

If you can't tell... We have a problem.

I would say the OP girls are pretty good examples of when you can't tell if they're young or old teens.

To me, they look like children.

I am keeping my eye on you too.

Because you only look at their faces?

You say their age. Is this a trick question? Kodomo no jikan girl is 10 if I remember.
>Not posting the big breasted one.

And right is probably 17.
