This is not the first time the Westboro clan has protested a died-in-the-wool conservative figure.
About 15 years ago the WB folks protested Bob Jones University, arguably one of the most conservative, anti-gay universities in the U.S.
Why?
Because apparently a gay alumnus set off a chain of events (I don't remember the details) that resulted in BJU having to allow gay people to visit it's museum of art... or some such.
Not understanding how a gay person could even graduate from Bob Jones, Fred Phelps screamed from the front gates, "When I was a student here the air was too pure for a faggot to breathe!"
