I'll preface this by saying that yes, I know some people really do have food allergies/intolerances and diseases that prevent them from eating certain foods. Some people really will die if they breathe peanut butter jar air.
However, I think a lot of this is blown out of proportion by the media and I think it's being used by the left wing to control people's lives.
When I was younger, I had NEVER heard of anybody who was allergic to peanuts. Almost every kid ate PB&Js and we would never have dreamed of going to school and being told we couldn't bring a PB&J because some other kid might keel over and die from it. When I first heard of this allergy 'epidemic' I quite frankly thought it was a bunch of BS propaganda. Even though I know some of the cases are real, it just seems like going way, way over the top for schools to ban peanut butter, etc. when that's a nutritious, energy-rich, and inexpensive food that doesn't go bad easily in bag lunches and doesn't harm most children who eat it. It also tends to appeal to picky eaters which many children are.
I read some other story about someone having to cut down their hickory tree because a neighbor's kid had a nut allergy and nuts MIGHT fall into their yard. The city was telling this person what to do with a tree on their own property that they'd had for years, because a neighbor had an allergy to tree nuts. Pine pollen makes me sick almost every Spring but I don't go around asking all the neighbors to chop down their pine trees. Why don't the parents of the kid pick up the nuts if the nuts are going to jump off the ground and attack their kid and force themselves into his mouth?
It all sounds like a big control issue. Like the city government says "you will bow to our will" and the government schools use it as an excuse to exert control over what kids bring for lunch. Is Peanut butter or nuts the new 'carbon dioxide' that liberals are going to pee themselves over?
If someone has an allergy, shouldn't they or their parents if it's a child be the ones to protect them, rather than everyone else having to kowtow and accommodate and allow their lives to be controlled?
