The nut jobs who are not Christian (they worship Satan I'm pretty sure if the SNL sketch I saw is correct) want to continue their protesting ways by hitting up militar funerals.
The response is VERY simple.
EVERY Westboro goes everyone needs to be aware of the best way to deal with them.
Fight presence with money.
Westboro has a list of hatred, take those organizations, and then raise money for them in direct opposition to the presence of Westboro.
Set up across the street and watch the dollars flow.
Eventually the money will speak louder than their bibles and westboro will see that they are a contributing funder for the org. they despise.
