Are you a prepper?

This whole zombie apocalypse thing is getting old.

On the real, if I were to go to someone's house and they had a bomb shelter and stock of assault rifles and canned goods to last for a decade, I would immediately know that that person was not on the same wavelength as me.

It's all cute to make the joke on the internet, but when did actually being crazy become socially acceptable?

It's due to the internet. Being able to find pockets of like minded edge cases all over makes almost every special/weird interest normal. From the benign like people that like to make sculptures out of fingernail clippings, to the political radicals that get bolder by finding each other on the internet. Once they can come out and get validation and confirmation from Nova Scotia or Florida, then they're bolder about talking about it in the "real" world.
