It isn't today, but this recent Friday, I saw a man with an appalling t-shirt.
I did NOT do anything over him to jeopardize my job. I did privately stew, and in fact later in the day I had a moment on my lunch break and my manager had me clock out early, BUT I didn't jeopardize my job.
That's the only angle I can profess as achievement. If I had not worry about my job, or any future job of mine, and if I weren't such a social coward, making him face wider-spread 1st Amendment backlash for how he chose to use his would have been a good start.
