I "Fully" support people prepping at what ever level they feel like prepping at.......Period.
However I feel there is a "possibility" things could get quite yucky. Those "zombies" you joke about, will be those who prepped for a shorter duration, then the duration of the event that happens.
If people want to joke about zombies, fine with me. If they want to belittle the more serious preppers who they see as.....silly serious and fearful of zombies, that also is fine with me.
But they should be keenly aware.........that part of prepping, includes "Hardening Your Heart" to face what you "might" need to do to protect yourself and your loved ones, from those who "WILL" become animals when it is clear to them, they did not prepare for a sufficient duration.
Hardening my Heart, has been an arduous training. I had the good fortune of that training started at about age nine or ten.
