Hate under the guise of God is what people like Bin Laden and Phelps preach.
Someone from VA Tech area should study how Phelps messed up recently and ended up paying for a Marine's funeral and make sure they get called if they make the same mistake.
Past this, PGR tactics are known to be effective and their will be no shortage of folks to hold flags and banners at the services for these students.
It is more fun for Phelps to threaten than to actually do. But, the preparations to deal with the Phelps crew are very helpful to the families so they are worth doing if the jerks show up or not.
