God Hates Shrimp is a site parody on the God Hates Fags losers.
From their About page:
As you may have realized, this site is a parody. It is meant to poke fun at people like Fred Phelps, and at people who protest against gay people and gay marriage.
The point we’re trying to make is that by using the Old Testament (specifically the book of Leviticus) as a basis for protesting gay marriage, you run into a couple of problems.
Well played, guys — well played.
