Reminds me of a summer I lived in Wyoming. People flipped me off quite frequently, and it was 100% because I had a BYU sticker on my car and they were just petty jerks. A few weeks later I realized I never actually put on the sticker, and I was just a bad driver.
This doesn't mean they wouldn't have flipped me off because of a BYU sticker, but just that it wasn't the case in this instance.
