I think you all may be going a little bit overboard on these suggestions. Given that we know nothing about this girl other than:
A. She's related to that asshole Fred Phelps
B. There's a picture of her carrying a very nasty sign (Does anyone have a date on that picture? I tried clicking the link to go back to the article, but it didn't work for me.)
I would at least try to find out what SHE thinks before slandering her/telling everyone else about her. Hell, maybe she's left the fold since that picture was taken. I would recommend trying to talk to her alone at some point and just asking her if she is related to Freddy and what she thinks about what he preaches.
Of course, if she does agree with Freddy, then let the games begin
Clever and witty signature to be inserted here, just as soon as I think of one.
