Survivalist Prepper Homesteader are they the Same?

I have written a new blog post on the new site called prepper life today.
And I would like to get your opinion on what I wrote I think that survivalist, prepper and homesteader is basically the same thing. They all are about becoming more self-sufficient the only difference is preppers and survivalists are preparing for disaster situations. And homesteader's are going for living off the grid.

But I think homesteaders are little more advanced because they know how to survive if there was a disaster. They did gardening making their own power and already store food for their families. I think all three can learn from each other.

I invite you to answer the question are survivalist's, Prepper's and Homesteader's are they the Same? or is there a major difference between the three of them.

I'm just starting out my blog called Prepper life today and would really like to get your opinion on this subject is kind of bothering me to know what really is the difference. Help me out by visiting my blog at http://prepperlifetoday.com

And leave me a comment on what you think.

Thanks Pete Balasch Jr.
