The Westboro Baptist Church {wiki} held a demonstration in front of the Twitter office in San Francisco on Thursday. Even more people showed up for a counter protest, featuring the best protest signs I've ever seen. See more signs at Laughing Squid. Link

That said, I saw a picture of one used at a counter-protest for a production of The Laramie Project that said "God Hates FarmVille." That one made me lol.
Wouldn't it just be easier for them to hold up signs saying "God hates everyone that isn't exactly like me"?
