It might be worthwhile to at least contemplate the possibility that identifying the places NOT do do business with might be safer - at least for the "conservative" businesses - in these times... if for no other reason than it does not provide the lazier elements of the left with a free list of potential targets all tied up with a nice bow. It isn't much fun to work hard to fly under the radar and suddenly have a friend (real or otherwise) blow the cover. Like people, companies vary on how much crap they can take before they buckle, as well as how far they want to act as lightning rods for any particular cause.
Sorry if that strikes anyone as paranoid, but "they" really ARE "out to get you."
