I don't get bothered by roaming evangelicals anymore once I stopped answering the door. If I'm not expecting someone, I don't bother answering. 99% of the time it's a salesman or a bible thumper anyways.
Yes and that last 1% of the time its someone trying to make the news.
We stopped answering the door and the phone (have a machine that does that for us) ... since we don't have friends that just drop in its never been anything but a positive for us.
