Our stadium here in Rochester has a nut-free section, and I appreciate that. And if we decide to sit elsewhere, then I'm 43 and I can handle myself if someone near us is eating peanuts. I don't like it, but I also don't make a scene (or even say anything) - we'll just move if there's space for us to do so or if the smell is particularly bad. It's not worth the aggravation on anyone's part for me to say anything, and as I said, I could have avoided it by sitting in the allocated section but chose not to do so. But that said, CF's point is spot on, as are all of his similar points about things like smoking. Is it "harder"? Yeah, maybe that's one perspective, but it's BETTER for everyone involved, and that's really the ultimate point. There are plenty of things/vices/foods that people do/eat/drink, or can do/eat/drink, that don't impact anyone. Want to eat an Almond Joy in my office? Go for it. Doesn't bother me in the least, because that doesn't affect my allergy. But a Snickers? Yeah, it does. Want a cigarette outside the building where other people have to walk? Fuck you. I spent a night in the hospital two years because I inadvertently ate a nut, and it fucked me up for a few days after that. Your right to enjoy a peanut at a baseball game doesn't supersede my right to breathe. Maybe banning peanuts at the ballpark is "too far" for some folks, but if it keeps people from having deadly allergic reactions, yeah, I'm down with that. Nobody's saying you can't have nuts, much like nobody's saying you can't smoke. You just can't do it in tight quarters where there's the potential for injury. Your right to swing your fist ends at the bridge of your neighbor's nose. Our neighbor has a windchime on their porch. DRIVES. ME. BANANAS. But it doesn't cause me any harm, so have at it, friend. But there's a difference between "doesn't cause harm" and "literally could kill someone."
