Some people have peanut allergies.
Newsflash: If you have a peanut allergy, don't take the airline peanuts.
There. Problem solved in the real world.
Washington is not the real world. According to the United States Government, People with peanut allergies are too stupid to refuse peanuts that may harm them. DOT wants to ban them.
How dumb, how totally arrogant does the Government have to get before we start repealing their authority to control every little thing?
