You are absolutely correct, and Banzhaf is one of the MAJOR culprits. He has already started suing fast food restaurants and says he will continue to do so until he gets a jury to agree with him, just like he did with the tobacco compaies.
He has actually BRAGGED about this technique on just about every major news network.
This man is evil and dangerous and smokers are just his guinea pigs. He is looking to see just how far he can go before the backlash occurs. However, because he has started with smokers he has pretty much gotten free reign because so many have fallen for his (and the rest of his anti-smoker cartel) BS about evil smokers most people refuse to look at the bigger picture which is that this will not stop with just the smokers.
A friend of mine was looking to change her insurance carrier and was denied a new insurance policy due to her weight. I seem to remember one State legislature trying to force restaurants to deny service to those considered overweight. (did I read that in here?, I don't have time for a search)
Now, some fast food restaurants are banning trans fats. Seems like big corporations are just rolling over and showing their bellies whenever they are threatened by special interests.
No, it will not stop with smokers. When it was allowed to happen to smokers, everyone just set themselves up.
