I’ll take “broad questions that can only be answered in context” for $200 Alex.

Seriously, ask me this question on 10 different days in 10 different ways and I’ll never give the same answer.

Even in the context of your vanilla perfume hypothetical I don’t have enough context to answer. How severe a reaction, what percentage of the population is affected, where is the perfume wearer at the time, why hasn’t it been banned and/or what makes me an expert who’s oppinion is worth a damn, etc etc etc?

From what little info I have on the hypothetical, no, I wouldn’t be upset. I didn’t see anyone being harmed, the perfume wearer wasn’t doing anything illegal, and I’ve got my own shit to deal with.
