Offense (like intent) exists only in a person's head & not in reality at all. There is zero harm in offending people. The freedom to cause offense is 100% necessary to the teaching/learning process. "Sticks & stones may break my bones, but words can never hurt me" is something people used to be taught from young ages. Now everyone has horrible personal boundaries because they are taught that how they feel is everyone else's responsibility rather than completely their own.
We are seeing the consequences of incorrect foundational belief systems playing out. If someone is afraid of getting sick, it's on them to stay home or protect themselves in whatever way they can, they can't require that everyone else stay home until they prove they are healthy. You can't externalize the cost of your fear onto everyone else & not be a tyrant. Sick until proven healthy is no different than calling people guilty until proven innocent. When people invert fundamental principles they transform life into hell, & many will almost deserve it.
