I do have to admit, I'm prepared for fires and earthquakes. Doomsday seems crazy, though. I have a bug out bag, etc... I'm not going to live under the preconceived notion that I'm going to survive a nuclear attack or race war that'll never happen. Pepper's get fucking insane. The number of people who start digging down without any understanding of structural integrity is insane aswell. Especially in places near fault lines. Building firebreaks, storing food and water, forming a microgrid if you live in an area where they might turn off the electricity, etc... those are all realistic and important. Also, fuck anti-maskers.
I lived in a small town on the New Madrid fault line in the middle of tornado alley most of my life and yep, we stocked up because we knew if a sizable enough earthquake hit the area, we were small enough to not get any attention for a long time while the nearby cities were recovering. There's definitely point of wisdom for sticking back supplies for a few months, but stacking a cellar full of tactical mil spec fishing poles and the like is mental masturbation for delusional assholes with less sense than money.
Technically just having a preparation in place for fires or earthquakes does make you a prepper. There may be varying degrees of it, but prepping for natural disasters is actually a much larger section of preppers than "zombies" or whatever bullshit. Hurricanes too in those areas is another common one, and you'd be surprised how many people carry and IFAK just in case of a car crash or shooter.
But any way you slice it, building firebreaks, storing food and water, and forming a microgrid, those are some good preparations my prepper friend.
