As someone pretty well marinating in "right wing" - based on where I live and the social circles I tend to run in - you're mostly right. They aren't mutually exclusive; you can have guns and friends at the same time. You can even have friends with guns.
Of course, but from what I can tell, all the "preppers" seem to know that they need to buy supplies and weapons, but all of that is useless if you are not part of a community tight knit enough to be willing to defend you, and that takes years of work to build up and constant maintenance of relationships.
There's a weird place between "preppers" and "homesteaders" that's pretty much this.
I'd say I'm "prepper" enough that I'm heavily armed and have enough shelf-stable food to feed by family for a few months in an emergency - but I'm also "homesteader" enough that our garden seems to get bigger each year, I know all of my neighbors, and we regularly share skills and information.
I don't think anything catastrophic is likely to happen, but it's had an overall very positive impact on my day-to-day life. If something does happen, I have far more tools to deal with it than either approach alone would give me.
You need friends and allies before you need guns.
