This weekend’s comic comes from Mr. Boffo. It’s dated July 17, 2013.
This is actually pretty pertinent to barefooters.
If they really don’t want zombies, they should put up a sign saying “No Zombies”.
A similar thing happened in the late 1960s, early 1970s. A lot of places didn’t want hippies (or, in some cases, blacks), but instead of putting up a “No Hippies” sign, they used shirt and shoes as a proxy and ended up banning more than their intended target. (We won’t get into whether this was fair or not). In the law, this is called “overbreadth”.
Eventually, people forgot why the signs were put up and just started assuming (when you “assume”, you make an “ass” out of “u” and “me”) that there were some phantom health codes, or they imagined some spate of barefoot lawsuits. But that wasn’t the case.
And we still end up fighting that ignorance today.
