I don't get it. Where exactly does it say he excluded her solely because of her faith? She's tossing the idea around, but I'm not seeing any evidence of it. Sure they reference a quote from way back in 1999 in which he expressed his opinion on Wicca, but a quote from 8 years ago and nothing else doesn't exactly make for compelling evidence. So she didn't get an invite but other people she knows did. What would you do in a situation like this? Ask why you didn't get the invite? Find out if it was an administrative oversight? Or contact the media and start screaming about how horribly you're being persecuted?
Personally, I would have just asked, but then again that would entail me having to actually talk to a representative of the Bush administration.
