A funny thing happens when I try to discuss with people the toxins that surround us. They posit my concern as a personal problem that I need help with — as if the real harm is the stress that such knowledge puts upon me. It’s an ingenious way for my audience to take their mind off the sad truth that we are bombarded with hundreds of carcinogenic and immune-suppressing chemicals daily. They can instead reframe the discussion as one about my emotional wellbeing, which simultaneously delegitimizes anything I say.
