Good reasoning, Reba.
It's the same reason I don't want any signage on my car. I'm a US Army vet, a life member of NRA, am planning to vote, and am deaf. How sad would it be if my wife were a victim of road rage by a driver who's anti-military or anti-gun? Someone who hates either or both '16 candidates? How about a surdophobic (someone with an unreasonable fear of deaf people)?
Hey, don't laugh. The crazies are everywhere! Even if you or a loved one escapes road rage, a delusional nut could decide to slash your tires.
