> No, which is why I’m not being insufferable

At this point you're interpreting genuine care and empathy for your brother's condition and appreciation for a hard-fought safety measure as chide. I remember when it was enacted. And a win for any of us is a win for all of us. Re-evaluate that assumption of yours.

You're right that a respiratory and contact allergy wouldn't benefit from food labels. Safety labels for folks like me would go on buildings, especially public spaces. And they would absolutely be helpful. The ADA does have some protections for folks with respiratory allergies in public spaces, but they're somewhat severely limited to a 6mo period after which filing an enforcement action is not possible. If you miss it, tough luck.

You are demonstrating to others the sort of attitude folks like your brother and I encounter constantly. So thanks for that. It's good for folks to see that just talking about the things that I and others like me experience and expressing care for others with similar conditions is enough to elicit hate. Because that's not uncommon. Most folks like me have dealt with that behavior, and nothing you say about me or my allergy will have any effect other than reflecting on yourself.
