Survivalist or Prepper

[John]

I am getting a little confused, probably my old age.
But is the difference between a ‘Survivalist’ and a ‘Prepper’.
It seems that a prepper is only a quite recent name and based on someone who prepares. And I suppose if you take the same line with a survivalist it would be someone who aims to survive.
So the question is, what is the difference between a ‘prepper’ and a ‘survivalist’.
