Now there's a petition out on the White House's We the People service to pressure Obama to take a stand and call out Indonesia on this injustice. If it gets 25,000 signatures, it will end up on his desk in the Oval Office. It's currently at about 3100, so there's a long way to go. Go. Sign. It.
In my opinion, any person who values freedom of expression, be they atheist or not, should be signing this.
As I said in my post on Skeptic Freethought about this issue: If you are an atheist and have ever expressed your views online, you would be a criminal in Indonesia. Atheism should not be a crime anywhere.
