It's not the ice cream that is dangerous. The danger is having the kids sit in front of the TV or computer for 4-6 hours a day.
One of my "guilty pleasures" is a daily bowl of ice cream. Not a huge one, but a bowl in any case.
It's not the consumption, it's the portion.
I agree with your post, however, inactivity is a contributor.
I have a 3 year old. She hasn't discovered the joy of veging (sp?) in front of the TV. I just can't keep her from climbing things (trees, furniture, etc). Hope she stays as active through her adolescence.
When my eight-year-old is watching TV, she can't hear the ice-cream truck until it is too late to stop it. So she plays outside, instead, where she can hear him coming from blocks away.
All in all, it's a fair trade, health wise. She gets a sweet treat, but she's out in God's sunshine all afternoon exercising it off.
Not nearly as dangerous as spending 8 hours in a public school.
What will it take for more to realize that the 'dream' these people share is documented as history's nightmare and ours as well.
For some, maybe the vanishing 'ice cream man' might be an awakening to the possibilities here. . .
OTOH, they might just think it is Bush's fault. .or worse, they might be grateful.
