I’ve never had an issue with a non-torch zippo lighter when going through TSA checks. Ive never had an issue with a zippo while going through airport security checks in Japan. I’ve had non-torch zippos confiscated while going through all the following airports: LHR, CDG, FRA, HAM, BCN, MAD.
Most airport security is theater sure, but the most egregious theatrics haven’t been from the TSA in my experience.
Oh man, Ingress was such a better game. I got slightly obsessed with it for a year or two. I had my entire state covered for a couple of days, before one of the nodes or whatever was broken.
