I consider anyone, who has a strong back ground in medicine, gardening/farming, ect to be a high value person in my AO. I don't care what their political affiliations or thoughts are.
They certainly need to be defended. They will help you survive if there is ever a coming collapse. Also, make those relationships NOW in your AO, before the collapse.
Ask your doctor questions like, what would you consider for payment if dollars became hyper inflated or worthless? Barter?
Ask your neighbor, the gardener the same type things. Ask if they'll let you come hang out and learn about gardening.
