Why do you think that? In reality people work together after disasters. If you think society is about to collapse then ok (and if say you were in Baghdad in 2003, you'd have been right).
But how many of us are in that situation?
A collapse so serious people start turning on each other is very rare.
Living as I do in sleepy, mild weathered, politically stable England I can think of no reason to be one.
As you say it seems a contradiction to publicise being a prepper. If you believe 'the starving mobs' will be looking for food, guess who they are going to head towards first?

And the idea of fortifying yourself seems ludicrous. If you never leave the house, maybe. Otherwise any predators will simply wait till you are outside it and bump you off. In the US where these imagined hoards can get hold of guns, even never going out isn't going to help.
Prepping in the sense of getting loads of guns and sitting out armageddon seems a fantasy for people who want to imagine they are mad max. If they really believed it was going to happen, being known as a prepper is the last thing they'd want.
