It's actually "Westboro" Baptist. And BTW they're not actually associated officially with the Baptists, they just call themselves that. Believe it or not, their website is www.godhatesfags.com. Yup, you read that right. And that "motorcycle gang" you referred call themselves the Patriot Guard Riders, and when they show up at funerals to protect the families, they do so as invited guests.
