For the sake of argument (and only for the sake of argument) let us say being overweight was a life style choice.
There are many life style choices people make that can cost society as a whole more if those choices were not made.
How about taking baths. Many accidents in the home occur in the bathtub.
How about smoking?
How about riding a motorcycle (with or without a helmet).
How about sexual activity. If we restricted sex to only married people and then only between their partners we can cut down on a lot of sexually transmitted diseases.
How about sporting events, how many people are injured playing baseball or football, and let us do not for get about skateboarding.
Every life style choice we make has some risk. Why condemn some but not all?
No man is an island. Those that think they are paying a cost for someone else's life style does not stop to realize someone else may be paying extra for theirs (how many people without children pay for public school?
You don't like fat people, fine, just don't pretend it is anything other than your own bias.
Airlines are a public business. They offer a service, transport a person from point A to point B for a price. If they had a rule that said no blacks could fly, they would be shut down in a second. If that is too strong for you, how about a sign that says "no one in the military could fly with them"? That is discrimination, pure and simple.
The airlines made a business decision, make seats smaller, and cram them closer together.
They then decided to demonize anyone that complains.
My dear friends here on FreeRepublic have jumpped on the band wagon and are helping them to demonize other American citizens, well all I got to say is shame on you, all of you.
Yes, create fewer and larger seats on the airlines and everyone pays higher ticket prices. Again, why should normal weight people pay higher prices to accommodate the obese.
