The most self-defeating PC sign I ever saw was back in my motorcycling days, when I used to zoom around the backcountry roads of New England at speeds that would have earned me 30 days in County.
So, I come around a curve and there’s a yellow sign that reads “Warning: Hearing-Impaired Child Living and Playing Ahead”.
My mental comment was, “Two words - Deaf Child - would accomplish the goal far better. By the time you’ve read and digested that bloated message, you’ve already run over the little tard.”
Sod PC.
