“Why aren’t you wearing red today?” The co-worker’s voice is shrill, sanctimonious righteousness dripping from her tone. “Don’t you know that wearing red today shows that you support women’s heart health?”
What I didn’t say, what I wish I’d said, was this: “Rather than exploit underpaid garment workers and line the pockets of clothing executives to show off how good a person I am, I’d rather actually support women’s heart health by supporting a living wage and universal health care so that all women could afford treatment and the more expensive healthy foods needed for cardiovascular health.
“But I guess it’s easier to buy a t-shirt.”
Probably best that you didn't. You would have looked like a total tool if it turned out that co-worker did all of those things AND wore the t-shirt.
