Wow, this thread is kind of dark, isn’t it?
I think the first strategy is to locate your home base somewhere that makes it rare for people to come by. Obviously, if you are stuck in an urban area, this isn’t feasible, but if you have a home in a rural area or a bugout location, then choosing something off the beaten path is best.
My thoughts on charity are pretty simple. I plan on giving the excess that I grow to the church and then directing people that need help to the church. I think simply turning people away from your personal property is enough, especially if they know there is a church in town that might be able to help them.
