I know nothing about hogs? So they aren't wild animals doing what wind animals do and eat things and protect their territory by being aggressive? If you can't handle living there with them then move...
They are not native, and they are spreading more than rats. A few more years and they will be every where in the US. Sorry I dont have the maps of how they have spread in the course of the last 10 years. If you would do some research in the problem you might have a little better of an idea what you are talking about.
