News articles refer to “Westboro Baptist Church” too.
True enough. Phelps and the Westboro Baptist Church identify themselves as Baptist, and claim to be following Primitive Baptist and Calvinist principles, though mainstream Primitive Baptists condemn Westboro Baptist Church and Phelps.
Given the above, it makes as much sense to add "Huckabee" and "Baptist" to the keywords of articles about Phelps and his rogue "church" as it does that "Romney", "Mormon", and "Romneytruthfile" have been added to the keywords of this thread. In either case, I'd consider it keyword abuse, but I guess it's not.
IIRC, you, like myself, aren't LDS. Just wanted to let you know that I think you're a real mensch for wading into the midst of threads like this one.
