As a Topeka resident, and a long-time opponent of the Phelps' Westboro Baptist 'Church,' I'd like to point out something that people often tend to miss when reacting to their offensive lunacy: It's a con job.
Fred Phelps has a long history of using his religious trappings to advance con games, from having his children sell "fund-raising" candy bars for which he never paid the candy companies, to advertising for a church organ and selling every one that was donated, and on and on. This is the most convoluted of his schemes, but to a large extent, it's just another con. Here's how it works:
1. There is a federal law (I believe it is the Equal Access to Justice Act) that mandates that legal fees and costs incurred in the process of suing the government to overturn a law on civil rights grounds (amongst other issues) must be paid by the governing body that passed the law.
2. Fred Phelps made his children attend law school, and many of them are practicing lawyers for Phelps Chartered law firm.
3. The Phelps cult shows up and engages in the most outrageous activities and uses the most offensive slogans they can come up with, usually targeted at a law that is Constitutionally vulnerable, like a flag desecration law or an anti-picketing ordinance.
4. If they are cited, they sue.
a.) If they lose, Fred pays nothing to his children. On to the next picket.
b.) If they win, Fred makes up whatever legal fees and billable hours he thinks he can get away with and hands a bill to the government.
5. Rinse and repeat.
Properly executed, it's a license to print money, provided one has no ethics, compassion, morality or soul. Which, of course, makes it the perfect scheme for "Reverend" Phelps.
