Be Easy -- Of course there are MANY MANY things as bad or worse than soda. And yes you are correct that there is a huge irony when schools replace sodas in vending machines with powerade etc... And yes there are many many things that the government can and should fix if they want to take this "healthier society stance".
But does all of that mean that this small measure is not a step in the right direction?
i see no benefit in replacing one evil with another
Conservative, n: A statesman who is enamored of existing evils, as distinguished from the Liberal who wishes to replace them with others.
like i said, i believe that good information trumps bullshit policy clouded with bad information. So long as the government perpetuates all the bad science and the bad information that goes along with it, a tax on soda serves no benefit to society, imo
